Merge tag 'staging-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree patches from Greg Kroah-Hartman:
 "Here's the big staging tree merge for the 3.6-rc1 merge window.

  There are some patches in here outside of drivers/staging/, notibly
  the iio code (which is still stradeling the staging / not staging
  boundry), the pstore code, and the tracing code.  All of these have
  gotten acks from the various subsystem maintainers to be included in
  this tree.  The pstore and tracing patches are related, and are coming
  here as they replace one of the android staging drivers.

  Otherwise, the normal staging mess.  Lots of cleanups and a few new
  drivers (some iio drivers, and the large csr wireless driver
  abomination.)

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

Fixed up trivial conflicts in drivers/staging/comedi/drivers/s626.h and
drivers/staging/gdm72xx/netlink_k.c

+	  chips.
+
+	  The sensor interface can be used to control the LEDs and backlights
+	  of the chip through defining five light zones and three sets of
+	  corresponding output-current values.
+
+	  The driver provides raw and mean adc readings along with the current
+	  light zone through sysfs. A threshold event can be generated on zone
+	  changes. The ALS-control output values can be set per zone for the
+	  three current output channels.
+
+config VCNL4000
+	tristate "VCNL4000 combined ALS and proximity sensor"
+	depends on I2C
+	help
+	 Say Y here if you want to build a driver for the Vishay VCNL4000
+	 combined ambient light and proximity sensor.
+
+	 To compile this driver as a module, choose M here: the
+	 module will be called vcnl4000.

 AI Triggering:
    For start_src == TRIG_EXT, the A/D EXTERNAL TRIGGER IN (pin 45) is used.
    For 1602 series, the start_arg is interpreted as follows:
-     start_arg == 0                   => gated triger (level high)
-     start_arg == CR_INVERT           => gated triger (level low)
+     start_arg == 0                   => gated trigger (level high)
+     start_arg == CR_INVERT           => gated trigger (level low)
      start_arg == CR_EDGE             => Rising edge
      start_arg == CR_EDGE | CR_INVERT => Falling edge
    For the other boards the trigger will be done on rising edge

+
+    NAME
+        CsrLogLevelTextSet
+
+    DESCRIPTION
+        Set the text logging level for a given origin and optionally sub origin
+        by name. If either string is NULL or zero length, it is interpreted as
+        all origins and/or all sub origins respectively. If originName is NULL
+        or zero length, subOriginName is ignored.
+
+        Passing NULL or zero length strings in both originName and subOriginName
+        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
+        previous filter configurations for all origins and sub origins.
+
+        Passing NULL or a zero length string in subOriginName overrides all
+        previous filter configurations for all sub origins of the specified
+        origin.
+
+        Note: the supplied strings may be accessed after the function returns
+        and must remain valid and constant until CsrLogDeinit is called.
+
+        Note: when specifying an origin (originName is not NULL and not zero
+        length), this function can only be used for origins that use the
+        csr_log_text_2.h interface for registration and logging. Filtering for
+        origins that use the legacy csr_log_text.h interface must be be
+        configured using the legacy filter configuration functions that accept
+        a CsrLogTextTaskId as origin specifier. However, when not specifying an
+        origin this function also affects origins that have been registered with
+        the legacy csr_log_text.h interface. Furthermore, using this function
+        and the legacy filter configuration functions on the same origin is not
+        allowed.
+
+    PARAMETERS
+        originName - a string containing the name of the origin. Can be NULL or
+            zero length to set the log level for all origins. In this case, the
+            subOriginName parameter will be ignored.
+        subOriginName - a string containing the name of the sub origin. Can be
+            NULL or zero length to set the log level for all sub origins of the
+            specified origin.
+        warningLevelMask - The desired log level for the specified origin(s) and
+            sub origin(s).

+ * - Function ----------------------------------------------------------------
+ * card_hw_init()
+ *
+ *      Perform the initialisation procedure described in the UniFi Host
+ *      Interface Protocol document (section 3.3.8) and read the run-time
+ *      configuration information from the UniFi. This is stuff like number
+ *      of bulk data slots etc.
+ *
+ *      The card enumeration and SD initialisation has already been done by
+ *      the SDIO library, see card_sdio_init().
+ *
+ *      The initialisation is done when firmware is ready, i.e. this may need
+ *      to be called after a f/w download operation.
+ *
+ *      The initialisation procedure goes like this:
+ *       - Wait for UniFi to start-up by polling SHARED_MAILBOX1
+ *       - Find the symbol table and look up SLT_SDIO_SLOT_CONFIG
+ *       - Read the config structure
+ *       - Check the "SDIO initialised" flag, if not zero do a h/w reset and
+ *         start again
+ *       - Decide the number of bulk data slots to allocate, allocate them and
+ *         set "SDIO initialised" flag (and generate an interrupt) to say so.
+ *
+ * Arguments:
+ *      card        Pointer to card struct
+ *
+ * Returns:
+ *      CSR_RESULT_SUCEESS on success,
+ *      a CSR error code on failure
+ *
+ * Notes:
+ *      All data in the f/w is stored in a little endian format, without any
+ *      padding bytes. Every read from this memory has to be transformed in
+ *      host (cpu specific) format, before it is stored in driver's parameters
+ *      or/and structures. Athough unifi_card_read16() and unifi_read32() do perform
+ *      the convertion internally, unifi_readn() does not.

+ *  send_signal
+ *
+ *      This function queues a signal for sending to UniFi.  It first checks

+ *      claims any bulk data slots required and copies data into them. Then
+ *      increments the fh_signal_queue write count.
+ *
+ *      The fh_signal_queue is later processed by the driver bottom half
+ *      (in unifi_bh()).
+ *
+ *      This function call unifi_pause_xmit() to pause the flow of data plane
+ *      packets when:
+ *        - the fh_signal_queue ring buffer is full
+ *        - there are less than UNIFI_MAX_DATA_REFERENCES (2) bulk data
+ *          slots available.
+ *
+ *  Arguments:
+ *      card            Pointer to card context structure
+ *      sigptr          Pointer to the signal to write to UniFi.
+ *      siglen          Number of bytes pointer to by sigptr.
+ *      bulkdata        Array of pointers to an associated bulk data.
+ *      sigq            To which from-host queue to add the signal.
+ *
+ *  Returns:
+ *      CSR_RESULT_SUCCESS on success
+ *      CSR_WIFI_HIP_RESULT_NO_SPACE if there were insufficient data slots or
+ *                              no free signal queue entry

+             * least one more check to see whether it needs to unpause the queue.  So all is well.

+
+  DESCRIPTION
+    Response from the application that received the NME SIM GSM AUTH IND. For
+    each GSM authentication round a GSM Ciphering key (Kc) and a signed
+    response (SRES) are produced. Since 2 or 3 GSM authentication rounds are
+    used the 2 or 3 Kc's obtained respectively are combined into one buffer
+    and similarly the 2 or 3 SRES's obtained are combined into another
+    buffer. The order of Kc values (SRES values respectively) in their buffer
+    is the same as that of their corresponding RAND values in the incoming
+    indication.
+
+  PARAMETERS
+    status     - Indicates the outcome of the requested operation:
+                 STATUS_SUCCESS or STATUS_ERROR
+    kcsLength  - Length in Bytes of Kc buffer. Legal values are: 16 or 24.
+    kcs        - Kc buffer holding 2 or 3 Kc values.
+    sresLength - Length in Bytes of SRES buffer. Legal values are: 8 or 12.

+
+  NAME
+    CsrWifiSmeConnectReqSend
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to start the
+    process of joining an 802.11 wireless network or to start an ad hoc
+    network.
+    The structure pointed by connectionConfig contains parameters describing
+    the network to join or, in case of an ad hoc network, to host or join.
+    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
+    and Associate exchanges.
+    The SME selects the networks from the current scan list that match both
+    the SSID and BSSID, however either or both of these may be the wildcard
+    value. Using this rule, the following operations are possible:
+      * To connect to a network by name, specify the SSID and set the BSSID to
+        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
+        the SME will select the one with the strongest signal.
+      * To connect to a specific network, specify the BSSID. The SSID is
+        optional, but if given it must match the SSID of the network. An empty
+        SSID may be specified by setting the SSID length to zero. Please note
+        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
+        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
+        poor, even if there is an alternative AP with an SSID that matches the
+        current network SSID.
+      * To connect to any network matching the other parameters (i.e. security,
+        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
+        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
+        by their signal strengths and will iterate through this list until it
+        successfully connects.
+    NOTE: Specifying the BSSID will restrict the selection to one specific
+    network. If SSID and BSSID are given, they must both match the network
+    for it to be selected. To select a network based on the SSID only, the
+    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
+    0xFF 0xFF.
+    The SME will try to connect to each network that matches the provided
+    parameters, one by one, until it succeeds or has tried unsuccessfully
+    with all the matching networks.
+    If there is no network that matches the parameters and the request allows
+    to host an ad hoc network, the SME will advertise a new ad hoc network
+    instead.

+  NAME
+    CsrWifiSmePacketFilterSetReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to enable or
+    disable filtering of broadcast packets: uninteresting broadcast packets
+    will be dropped by the Wi-Fi chip, instead of passing them up to the
+    host.
+    This has the advantage of saving power in the host application processor
+    as it removes the need to process unwanted packets.
+    All broadcast packets are filtered according to the filter and the filter
+    mode provided, except ARP packets, which are filtered using
+    arpFilterAddress.
+    Filters are not cumulative: only the parameters specified in the most
+    recent successful request are significant.
+    For more information, see 'UniFi Firmware API Specification'.
+
+  PARAMETERS
+    queue            - Message Source Task Queue (Cfm's will be sent to this Queue)
+    interfaceTag     - Interface Identifier; unique identifier of an interface
+    filterLength     - Length of the filter in bytes.
+                       filterLength=0 disables the filter previously set
+    filter           - Points to the first byte of the filter provided, if any.

+                       information elements of one of these types

+                         * WMM-SA TCLAS elements
+    mode             - Specifies whether the filter selects or excludes packets
+                       matching the filter
+    arpFilterAddress - IPv4 address to be used for filtering the ARP packets.
+                         * If the specified address is the IPv4 broadcast address
+                           (255.255.255.255), all ARP packets are reported to the

+
+  DESCRIPTION
+    The SME will send this primitive to all the tasks that have registered to

+    If the wireless manager application connect request specified the SSID
+    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
+    0xFF), the SME monitors the signal quality and maintains a list of
+    candidates to roam to. When the signal quality of the current connection
+    falls below a threshold, and there is a candidate with better quality,
+    the SME will attempt to the candidate AP.
+    If the roaming procedure succeeds, the SME will also issue a Media
+    Connect indication to inform the wireless manager application of the
+    change.
+    NOTE: to prevent the SME from initiating roaming the WMA must specify the
+    BSSID in the connection request; this forces the SME to connect only to
+    that AP.
+    The wireless manager application can obtain statistics for roaming
+    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
+    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
+    When the wireless manager application wishes to roam to another AP, it

+    Channels are scanned actively or passively according to the requirement
+    set by regulatory domain.
+    If the SME receives this primitive while a full scan is going on, the new

+    ssidCount        - Number of SSIDs provided.
+                       If it is 0, the SME will attempt to detect any network
+    ssid             - Points to the first SSID provided, if any.
+    bssid            - BSS identifier.
+                       If it is equal to FF-FF-FF-FF-FF, the SME will listen for

+
+  NAME
+    CsrWifiSmeTspecReqSend
+
+  DESCRIPTION
+    The wireless manager application should call this primitive to use the
+    TSPEC feature.
+    The chip supports the use of TSPECs and TCLAS for the use of IEEE
+    802.11/WMM Quality of Service features.
+    The API allows the wireless manager application to supply a correctly
+    formatted TSPEC and TCLAS pair to the driver.
+    After performing basic validation, the driver negotiates the installation
+    of the TSPEC with the AP as defined by the 802.11 specification.
+    The driver retains all TSPEC and TCLAS pairs until they are specifically
+    removed.
+    It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
+    indicate that no TCLAS is supplied), while a TCLASS always require a
+    TSPEC.
+    The format of the TSPEC element is specified in 'WMM (including WMM Power
+    Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.
+    For more information, see 'UniFi Configuring WMM and WMM-PS'.

+
+  NAME
+    CsrWifiSmeWifiFlightmodeReqSend
+
+  DESCRIPTION
+    The wireless manager application may call this primitive on boot-up of
+    the platform to ensure that the chip is placed in a mode that prevents
+    any emission of RF energy.
+    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
+    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
+    (if any) and the programming of the initial MIB settings (if supplied by
+    the WMA), but it also ensures that the chip is left in its lowest
+    possible power-mode with the radio subsystems disabled.
+    This feature is useful on platforms where power cannot be removed from
+    the chip (leaving the chip not initialised will cause it to consume more
+    power so calling this function ensures that the chip is initialised into
+    a low power mode but without entering a state where it could emit any RF
+    energy).
+    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
+    stays conceptually off. Configuration primitives can be sent after
+    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
+    Requests that require the state of the Wi-Fi to be ON will return
+    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.
+
+  PARAMETERS
+    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
+    address       - Optionally specifies a station MAC address.
+                    In normal use, the manager should set the address to 0xFF
+                    0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
+                    the MAC address in the MIB.
+    mibFilesCount - Number of provided data blocks with initial MIB values
+    mibFiles      - Points to the first data block with initial MIB values.
+                    These data blocks are typically the contents of the provided
+                    files ufmib.dat and localmib.dat, available from the host
+                    file system, if they exist.
+                    These files typically contain radio tuning and calibration
+                    values.
+                    More values can be created using the Host Tools.

+
+  NAME
+    CsrWifiSmeWifiOnReqSend
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to turn on the
+    Wi-Fi chip.
+    If the Wi-Fi chip is currently off, the SME turns the Wi-Fi chip on,
+    downloads the patch file (if any), and programs the initial MIB settings
+    (if supplied by the WMA).
+    The patch file is not provided with the SME API; its downloading is
+    automatic and handled internally by the system.
+    The MIB settings, when provided, override the default values that the
+    firmware loads from EEPROM.
+    If the Wi-Fi chip is already on, the SME takes no action and returns a
+    successful status in the confirm.
+
+  PARAMETERS
+    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
+    address       - Optionally specifies a station MAC address.
+                    In normal use, the manager should set the address to 0xFF
+                    0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
+                    the MAC address in the MIB
+    mibFilesCount - Number of provided data blocks with initial MIB values
+    mibFiles      - Points to the first data block with initial MIB values.
+                    These data blocks are typically the contents of the provided
+                    files ufmib.dat and localmib.dat, available from the host
+                    file system, if they exist.
+                    These files typically contain radio tuning and calibration
+                    values.
+                    More values can be created using the Host Tools.

+
+  NAME
+    CsrWifiSmeConnectReq
+
+  DESCRIPTION
+    The wireless manager application calls this primitive to start the
+    process of joining an 802.11 wireless network or to start an ad hoc
+    network.
+    The structure pointed by connectionConfig contains parameters describing
+    the network to join or, in case of an ad hoc network, to host or join.
+    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
+    and Associate exchanges.
+    The SME selects the networks from the current scan list that match both
+    the SSID and BSSID, however either or both of these may be the wildcard
+    value. Using this rule, the following operations are possible:
+      * To connect to a network by name, specify the SSID and set the BSSID to
+        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
+        the SME will select the one with the strongest signal.
+      * To connect to a specific network, specify the BSSID. The SSID is
+        optional, but if given it must match the SSID of the network. An empty
+        SSID may be specified by setting the SSID length to zero. Please note
+        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
+        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
+        poor, even if there is an alternative AP with an SSID that matches the
+        current network SSID.
+      * To connect to any network matching the other parameters (i.e. security,
+        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
+        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
+        by their signal strengths and will iterate through this list until it
+        successfully connects.
+    NOTE: Specifying the BSSID will restrict the selection to one specific
+    network. If SSID and BSSID are given, they must both match the network
+    for it to be selected. To select a network based on the SSID only, the
+    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
+    0xFF 0xFF.
+    The SME will try to connect to each network that matches the provided
+    parameters, one by one, until it succeeds or has tried unsuccessfully
+    with all the matching networks.
+    If there is no network that matches the parameters and the request allows
+    to host an ad hoc network, the SME will advertise a new ad hoc network
+    instead.
+    If the SME cannot connect, it will notify the failure in the confirm.

+    The wireless manager application should call this primitive to use the

+    The chip supports the use of TSPECs and TCLAS for the use of IEEE
+    802.11/WMM Quality of Service features.
+    The API allows the wireless manager application to supply a correctly
+    formatted TSPEC and TCLAS pair to the driver.
+    After performing basic validation, the driver negotiates the installation
+    of the TSPEC with the AP as defined by the 802.11 specification.
+    The driver retains all TSPEC and TCLAS pairs until they are specifically
+    removed.
+    It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
+    indicate that no TCLAS is supplied), while a TCLASS always require a
+    TSPEC.
+    The format of the TSPEC element is specified in 'WMM (including WMM Power
+    Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.

+
+  DESCRIPTION
+    The wireless manager application may call this primitive on boot-up of
+    the platform to ensure that the chip is placed in a mode that prevents
+    any emission of RF energy.
+    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
+    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
+    (if any) and the programming of the initial MIB settings (if supplied by
+    the WMA), but it also ensures that the chip is left in its lowest
+    possible power-mode with the radio subsystems disabled.
+    This feature is useful on platforms where power cannot be removed from
+    the chip (leaving the chip not initialised will cause it to consume more
+    power so calling this function ensures that the chip is initialised into
+    a low power mode but without entering a state where it could emit any RF
+    energy).
+    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
+    stays conceptually off. Configuration primitives can be sent after
+    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
+    Requests that require the state of the Wi-Fi to be ON will return
+    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.

+    The SME will send this primitive to all the tasks that have registered to

+    If the wireless manager application connect request specified the SSID
+    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
+    0xFF), the SME monitors the signal quality and maintains a list of
+    candidates to roam to. When the signal quality of the current connection
+    falls below a threshold, and there is a candidate with better quality,
+    the SME will attempt to the candidate AP.
+    If the roaming procedure succeeds, the SME will also issue a Media
+    Connect indication to inform the wireless manager application of the
+    change.
+    NOTE: to prevent the SME from initiating roaming the WMA must specify the
+    BSSID in the connection request; this forces the SME to connect only to
+    that AP.
+    The wireless manager application can obtain statistics for roaming
+    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
+    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
+    When the wireless manager application wishes to roam to another AP, it
+    must issue a connection request specifying the BSSID of the desired AP.

+ * Porting Notes:
+ * Part of this file contains an example for how to glue the OS layer
+ * with the HIP core lib, the SDIO glue layer, and the SME.
+ *
+ * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load().
+ * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue
+ * layer. uf_sdio_load() registers this driver with the underlying SDIO driver.
+ * When a card is detected, the SDIO glue layer calls register_unifi_sdio()
+ * to pass the SDIO function context and ask the OS layer to initialise
+ * the card. register_unifi_sdio() allocates all the private data of the OS
+ * layer and calls uf_run_unifihelper() to start the SME. The SME calls
+ * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card.

+ *  FILE:     io.c
+ *
+ *  PURPOSE:
+ *      This file contains routines that the SDIO driver can call when a
+ *      UniFi card is first inserted (or detected) and removed.
+ *
+ *      When used with sdioemb, the udev scripts (at least on Ubuntu) don't
+ *      recognise a UniFi being added to the system. This is because sdioemb
+ *      does not register itself as a device_driver, it uses it's own code
+ *      to handle insert and remove.
+ *      To have Ubuntu recognise UniFi, edit /etc/udev/rules.d/85-ifupdown.rules
+ *      to change this line:
+ *          SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
+ *      to these:
+ *          #SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
+ *          SUBSYSTEM=="net", GOTO="net_start"
+ *
+ *      Then you can add a stanza to /etc/network/interfaces like this:
+ *          auto eth1
+ *          iface eth1 inet dhcp
+ *          wpa-conf /etc/wpa_supplicant.conf
+ *      This will then automatically associate when a car dis inserted.
+ *

+ *      This function waits for a specific (sig_reply_id) signal from UniFi.
+ *      It also match the sequence number of the received (cfm) signal, with
+ *      the latest sequence number of the signal (req) we have sent.
+ *      These two number match be equal.
+ *      Should only be used for waiting xxx.cfm signals and only after
+ *      we have sent the matching xxx.req signal to UniFi.
+ *      If no response is received within the expected time (timeout), we assume
+ *      that the UniFi is busy and return an error.
+ *      If the wait is aborted by a kernel signal arriving, we stop waiting.
+ *      If a response from UniFi is not what we expected, we discard it and
+ *      wait again. This could be a response from an aborted request. If we
+ *      see several bad responses we assume we have lost synchronisation with
+ *      UniFi.

+/*
+ * Porting Notes:
+ * This file implements the data plane of the UniFi linux driver.
+ *
+ * All the Tx packets are passed to the HIP core lib, using the
+ * unifi_send_signal() API. For EAPOL packets use the MLME-EAPOL.req
+ * signal, for all other use the MLME-UNITDATA.req. The unifi_send_signal()
+ * expects the wire-formatted (packed) signal. For convenience, in the OS
+ * layer we only use the native (unpacked) signal structures. The HIP core lib
+ * provides the write_pack() helper function to convert to the packed signal.
+ * The packet is stored in the bulk data of the signal. We do not need to
+ * allocate new memory to store the packet, because unifi_net_data_malloc()
+ * is implemented to return a skb, which is the format of packet in Linux.
+ * The HIP core lib frees the bulk data buffers, so we do not need to do
+ * this in the OS layer.
+ *
+ * All the Rx packets are MLME-UNITDATA.ind signals, passed by the HIP core lib
+ * in unifi_receive_event(). We do not need to allocate an skb and copy the
+ * received packet because the HIP core lib has stored in memory allocated by
+ * unifi_net_data_malloc(). Also, we can perform the 802.11 to Ethernet
+ * translation in-place because we allocate the extra memory allocated in
+ * unifi_net_data_malloc().
+ *
+ * If possible, the porting exercise should appropriately implement
+ * unifi_net_data_malloc() and unifi_net_data_free() to save copies between
+ * network and driver buffers.

+ * This file also contains the implementation of the asyncronous
+ * requests to the SME.
+ *
+ * Before calling an asyncronous SME function, we call sme_init_request()
+ * which gets hold of the SME semaphore and updates the request status.
+ * The semaphore makes sure that there is only one pending request to
+ * the SME at a time.
+ *
+ * Now we are ready to call the SME function, but only if
+ * sme_init_request() has returned 0.
+ *
+ * When the SME function returns, we need to wait
+ * for the reply. This is done in sme_wait_for_reply().
+ * If the request times-out, the request status is set to SME_REQUEST_TIMEDOUT
+ * and the sme_wait_for_reply() returns.
+ *
+ * If the SME replies in time, we call sme_complete_request().
+ * There we change the request status to SME_REQUEST_RECEIVED. This will
+ * wake up the process waiting on sme_wait_for_reply().
+ * It is important that we copy the reply data in priv->sme_reply
+ * before calling sme_complete_request().
+ *
+ * Handling the wext requests, we need to block
+ * until the SME sends the response to our request.
+ * We use the sme_init_request() and sme_wait_for_reply()
+ * to implement this behavior in the following functions:
+ * sme_mgt_wifi_on()
+ * sme_mgt_wifi_off()
+ * sme_mgt_scan_full()
+ * sme_mgt_scan_results_get_async()

+ *  Returns:

+ *
+ *  Notes:
+ *  The signals are received in the format described in the host interface
+ *  specification, i.e wire formatted. Certain clients use the same format
+ *  to interpret them and other clients use the host formatted structures.
+ *  Each client has to call read_unpack_signal() to transform the wire
+ *  formatted signal into the host formatted signal, if necessary.
+ *  The code is in the core, since the signals are defined therefore

+* Texas Instrument OMAP SCM bandgap bindings
+
+In the System Control Module, OMAP supplies a voltage reference
+and a temperature sensor feature that are gathered in the band
+gap voltage and temperature sensor (VBGAPTS) module. The band
+gap provides current and voltage reference for its internal
+circuits and other analog IP blocks. The analog-to-digital
+converter (ADC) produces an output value that is proportional
+to the silicon temperature.
+
+Required properties:
+- compatible : Should be:
+  - "ti,omap4460-control-bandgap" : for OMAP4460 bandgap
+  - "ti,omap5430-control-bandgap" : for OMAP5430 bandgap
+- interrupts : this entry should indicate which interrupt line
+the talert signal is routed to;
+Specific:
+- ti,tshut-gpio : this entry should be used to inform which GPIO
+line the tshut signal is routed to;
+
+Example:
+
+bandgap {
+	reg = <0x4a002260 0x4
+		0x4a00232C 0x4
+		0x4a002378 0x18>;
+	compatible = "ti,omap4460-control-bandgap";
+	interrupts = <0 126 4>; /* talert */
+	ti,tshut-gpio = <86>;
+};

 TODO:
-	- review user mode interface and determine if ioctls can be replaced
-	  with something better. correctly export data structures to user mode
-	  if ioctls are still required and allocate ioctl numbers from
-	  ioctl-number.txt.
+	- Convert event tracing code to in-kernel tracing infrastructure
+	- Check for remaining ioctl & check if that can be converted into
+	  sysfs entries
+	- Convert debug prints to appropriate dev_debug or something better
+	- Modify Kconfig to add CONFIG option for enabling/disabling event
+	  tracing.
 	- check USB HCD implementation is complete and correct.
-	- remove any debug and trace code.
 	- code review by USB developer community.
 	- testing with as many devices as possible.

+ * This allocator is designed for use with zcache and zram. Thus, the
+ * allocator is supposed to work well under low memory conditions. In
+ * particular, it never attempts higher order page allocation which is
+ * very likely to fail under memory pressure. On the other hand, if we
+ * just use single (0-order) pages, it would suffer from very high
+ * fragmentation -- any object of size PAGE_SIZE/2 or larger would occupy
+ * an entire page. This was one of the major issues with its predecessor
+ * (xvmalloc).
+ *
+ * To overcome these issues, zsmalloc allocates a bunch of 0-order pages
+ * and links them together using various 'struct page' fields. These linked
+ * pages act as a single higher-order page i.e. an object can span 0-order
+ * page boundaries. The code refers to these linked pages as a single entity
+ * called zspage.
+ *
+ * Following is how we use various fields and flags of underlying
+ * struct page(s) to form a zspage.
+ *
+ * Usage of struct page fields:
+ *	page->first_page: points to the first component (0-order) page
+ *	page->index (union with page->freelist): offset of the first object
+ *		starting in this page. For the first page, this is
+ *		always 0, so we use this field (aka freelist) to point
+ *		to the first free object in zspage.
+ *	page->lru: links together all component pages (except the first page)
+ *		of a zspage
+ *
+ *	For _first_ page only:
+ *
+ *	page->private (union with page->first_page): refers to the
+ *		component page after the first page
+ *	page->freelist: points to the first free object in zspage.
+ *		Free objects are linked together using in-place
+ *		metadata.
+ *	page->objects: maximum number of objects we can store in this
+ *		zspage (class->zspage_order * PAGE_SIZE / class->size)
+ *	page->lru: links together first pages of various zspages.
+ *		Basically forming list of zspages in a fullness group.
+ *	page->mapping: class index and fullness group of the zspage
+ *
+ * Usage of struct page flags:
+ *	PG_private: identifies the first component page
+ *	PG_private2: identifies the last component page
