Denys Vlasenko f86dec94e3 NFC: hci: delete unused nfc_llc_get_rx_head_tail_room()
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.

Christophe Ricard 15d17170b4 NFC: st21nfca: Add support for proprietary commands
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.

Jeff Kirsher 98b32decc8 nfc: Fix FSF address in file headers
Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.

Eric Lapuyade 4a61cd6687 NFC: Add an shdlc llc module to llc core

communications between HCI and the chip to use shdlc.

Eric Lapuyade 8af00d48dc NFC: Add a nop (passthrough) llc module to llc core
This is a passthrough llc. It can be used by HCI drivers that don't
need link layer control. HCI will then write directly to the driver, and
driver will deliver incoming frames directly to HCI without any
processing.

Eric Lapuyade 67cccfe17d NFC: Add an LLC Core layer to HCI
The LLC layer manages modules that control the link layer protocol (such
as shdlc) between HCI and an HCI driver. The driver must simply specify
the required llc when it registers with HCI.
