NFC: hci: delete unused nfc_llc_get_rx_head_tail_room()

2016-07-04T10:14:05+00:00

It used to be EXPORTed, but then EXPORT usage was cleaned up
(in 2012), without noticing that the function has no users at all
(and curiously, never had any users).

Delete it.

While at it, remove non-static "inline" hints on nearby functions:
these hints don't work across compilation units anyway,
and these functions are not used in their .c file, thus they are
never inlined. IOW: "inline" here does not help in any way.

NFC: st21nfca: Add support for proprietary commands

2015-10-27T03:00:24+00:00

Add support for proprietary commands useful mainly
for factory testings.

Here is a list:

- FACTORY_MODE: Allow to set the driver into a mode where no
  secure element are activated. It does not consider any
  NFC_ATTR_VENDOR_DATA.
- HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes
  command. It does not consider any NFC_ATTR_VENDOR_DATA.
- HCI_DM_PUT_DATA: Allow to configure specific CLF registry as
  for example RF trimmings or low level drivers configurations
  (I2C, SPI, SWP).
- HCI_DM_UPDATE_AID: Allow to configure an AID routing into the
  CLF routing table following RF technology, CLF mode or protocol.
- HCI_DM_GET_INFO: Allow to retrieve CLF information.
- HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as
  low level drivers configurations or RF trimmings.
- HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete
  packet can be more than 8KB.
- HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
  configuration changes without CLF power off.
- HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
  the white list).
- HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
  technology. When using this command to anti-collision is done.
- HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
  connectivity.

NFC: netlink: Add mode parameter to deactivate_target functions

2015-10-27T02:55:12+00:00

In order to manage in a better way the nci poll mode state machine,
add mode parameter to deactivate_target functions.
This way we can manage different target state.
mode parameter make sense only in nci core.

NFC: hci: Remove nfc_hci_pipe2gate function

2015-01-27T23:03:36+00:00

With the newly introduced pipes table hci_dev fields,
the nfc_hci_pipe2gate routine is no longer needed.

NFC: hci: Add cmd_received handler

2015-01-27T23:03:34+00:00

When a command is received, it is sometime needed to let the CLF driver do
some additional operations. (ex: count remaining pipe notification...)

NFC: hci: Reference every pipe information according to notification

2015-01-27T23:03:29+00:00

We update the tracked pipes status when receiving HCI commands.
Also we forward HCI errors and we reply to any HCI command, even though
we don't support it.

NFC: hci: Change nfc_hci_send_response gate parameter to pipe

2015-01-27T22:55:20+00:00

As there can be several pipes connected to the same gate, we need
to know which pipe ID to use when sending an HCI response. A gate
ID is not enough.

Instead of changing the nfc_hci_send_response() API to something
not aligned with the rest of the HCI API, we call nfc_hci_hcp_message_tx
directly.

NFC: hci: Add pipes table to reference them with a tuple {gate, host}

2015-01-27T22:39:32+00:00

In order to keep host source information on specific hci event (such as
evt_connectivity or evt_transaction) and because 2 pipes can be connected
to the same gate, it is necessary to add a table referencing every pipe
with a {gate, host} tuple.

NFC: hci: Change event_received handler gate parameter to pipe

2015-01-27T22:39:23+00:00

Several pipes may point to the same CLF gate, so getting the gate ID
as an input is not enough.
For example dual secure element may have 2 pipes (1 for uicc and
1 for eSE) pointing to the connectivity gate.

As resolving gate and host IDs can be done from a pipe, we now pass
the pipe ID to the event received handler.

NFC: hci: Add specific hci macro to not create a pipe

2014-12-02T21:48:13+00:00

Some pipe are only created by other host (different than the
Terminal Host).
The pipe values will for example be notified by
NFC_HCI_ADM_NOTIFY_PIPE_CREATED.
