NFC: Separate pn544 hci driver in HW dependant and independant parts The driver now has all HCI stuff isolated in one file, and all the hardware link specifics in another. Writing a pn544 driver on top of another hardware link is now just a matter of adding a new file for that new hardware specifics.

NFC: pn544: i2c: Add firmware download mode power-on support This is in preparation for pn544-i2c firmware download feature, where we need to know if we're in regular or firmware upload mode. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

NFC: pn544: Pass hardware variant information when downloading firmware Different pn544 hardware variant may use different commands to download new firmwares. The C2 does a regular firmware download while the C3 uses a more secure protocol. As a consequence we need to pass the hardware variant from the HCI SW version command reply down to the pn544 i2c layer, in order to use the right protocol at run time.
