2013-04-11NFC: pn533: Add pn533_abort_cmd procedureWaldemar Rymarkiewicz
pn533_abort_cmd() aborts last command sent to the controller and cancels already requested urb. As ACR122U does not support any mechanism (as ACK for standard PN533) which aborts last command this cannot be issued for this device. Otherwise, acr122u will behave in an unstable way.

2013-04-11NFC: pn533: Add support for ACS ACR122U readerWaldemar Rymarkiewicz
ACS ACR122U is an USB NFC reader, PC/SC and CCID compilant, based on NXP PN532 chip. Internally, it's build of MCU, PN532 and an antenna. MCU makes the device CCID and PC/SC compilant and provide USB connection. In this achitecture, a host cannot talk directly to PN532 and must rely on MCU. Luckily, MCU exposes pseud-APDU through PC/SC Escape mechanism which let the host to transmit standard PN532 commands directly to PN532 chip with some limitations. The frame roughly looks like: CCID header | APDU header | PN532 header (pc_to_rdr_escape) | (pseudo apdu Direct Tramsmit) | (len, TFI, cmd, params) Accordign to limitations, ACR122U does't provide any mechanism to abort last issued command.

2013-04-11NFC: pn533: Simplify __pn533_send_frame_asyncWaldemar Rymarkiewicz
In all cases (send_cmd_async, send_data_async and send_sync) pn533_send_async_complete() handles all responses internally, so there is no need to pass this as a callback. Cmd context is passed to __pn533_send_frame_async in all the cases as well. It's already kept in struct pn533 which is available all the time the device is attached. So we can make use of it instead. Therefore, cmd_complete and cmd_complete_arg are no needed any more. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-04-11NFC: pn533: Optimise issued cmd context trackingWaldemar Rymarkiewicz
Use struct pn533_cmd instead of pn533_send_async_complete_arg to track the context of the issued cmd. This way pn533_send_async_complete_arg struct is no needed anymore.
