The port100 already supports NFC-A and ATS request and response for type 4A tags are handled at digital level. This patch adds NFC_PROTO_ISO14443 to the supported protocols and an entry for framing configuration which is the same as NFC-A standard frame with CRC handling.

NFC: port100: Commands mechanism implementation 2013-10-07T12:10:52+00:00 Thierry Escande thierry.escande@linux.intel.com 2013-10-04T10:12:01+00:00 0347a6ab300a1532c298823408d6e51ccf4e4f45 This patch implements the command handling mechanism. The digital stack serializes all commands sent to the driver. This means that the digital stack waits for the reply of the current command before sending a new one. So there is no command queue managed at driver level. All Port-100 commands are asynchronous. If the command has been sent successfully to the device, it replies with an ACK frame. Then the command response is received (or actually no-response in case of timeout or error) and a command complete work on the system workqueue is responsible for sending the response (or the error) back to the digital stack. The digital stack requires some commands to be synchronous, mainly hardware configuration ones. These commands use the asynchronous command path but are made synchronous by using a completion object.

This dongle is an analog frontend and does not implement the digital layer. This driver uses the nfc_digital module which is an implementation of the NFC Digital Protocol stack. This patch is a skeleton. It only registers the dongle against the NFC digital protocol stack. All NFC digital operation functions are stubbed out.
