nfc.h being GPL makes it quite controversial for non GPL applications to include it. Moreover, nfc.h only includes structures and API definitions that are hardly copyrightable. Signed-off-by: Lauro Ramos Venancio <lauro.venancio@openbossa.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* @NFC_CMD_DEV_UP: turn on the nfc device
|

* %NFC_ATTR_DEVICE_INDEX)

* (it sends %NFC_ATTR_DEVICE_INDEX)

|
|
* from target mode.
|

* @NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device
|

* @NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for
|
|
* a device. LTO must be set before the link is up otherwise -EINPROGRESS

* Once enabled a secure element will handle card emulation mode, i.e.

|
* starting a poll from a device which has a secure element enabled means
|
|
* we want to do SE based card emulation.
