Problem is that all the API are not ready yet for it. Problem is that with current code, when neard asks to deactivate the tag it sends a deactivate SLEEP but nobody will then send a IDLE deactivate. This IDLE deactivate is mandatory since NFC controller can only be unlocked by DH. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

As with SPI, a lot of code can be shared between vendor drivers. This patch add the generic support of UART and provides some extension API for vendor specific needs. This code is strongly inspired by the Bluetooth HCI ldisc implementation. NCI UART vendor drivers will have to register themselves to this layer via nci_uart_register.

Drivers will associate a set of vendor commands to a vendor id, which could typically be an OUI. The netlink kernel implementation will try to match the received vendor id and sub command attributes with the registered ones. When such match is found, the driver defined sub command routine is called. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
