NFC: nci: non-static functions can not be inline

2015-10-28T05:44:45+00:00

This fixes a build error that seems to be toochain

NFC: NCI: allow spi driver to choose transfer clock

2015-10-27T03:23:34+00:00

In some cases low level drivers might want to update the
SPI transfer clock (e.g. during firmware download).

This patch adds this support. Without any modification the
driver will use the default SPI clock (from pdata or device tree).

NFC: NCI: export nci_send_frame and nci_send_cmd function

2015-10-27T03:16:14+00:00

Export nci_send_frame and nci_send_cmd symbols to allow drivers
to use it. This is needed for example if NCI is used during
firmware download phase.

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: st-nci: Add support for proprietary commands

2015-10-27T02:55:01+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
  like 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_DIRECT_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.
- HCI_DM_VDC_MEASUREMENT_VALUE: Allow to measure the field applied
  on the CLF antenna. A value between 0 and 0x0f is returned. 0 is
  maximum.
- HCI_DM_FWUPD_START: Allow to put CLF into firmware update mode.
  It is a specific CLF command as there is no GPIO for this.
- HCI_DM_FWUPD_END:  Allow to complete firmware update.
- HCI_DM_VDC_VALUE_COMPARISON: Allow to compare the field applied
  on the CLF antenna to a reference value.
- MANUFACTURER_SPECIFIC: Allow to retrieve manufacturer specific data
  received during a NCI_CORE_INIT_CMD.

NFC: st-nci: Add support for NCI_HCI_IDENTITY_MGMT_GATE

2015-10-26T05:53:16+00:00

NCI_HCI_IDENTITY_MGMT_GATE might be useful to get information
about hardware or firmware version.

for example after a firmware update.

NFC: nci: add nci_get_conn_info_by_id function

2015-10-25T19:29:11+00:00

This functin takes as a parameter a pointer to the nci_dev
struct and the first byte from the values of the first domain
specific parameter that was used for the connection creation.
