NFC: pn544: Pass hardware variant information when downloading firmware 2014-02-16T22:49:54+00:00 Arron Wang arron.wang@intel.com 2013-12-11T09:25:23+00:00 971d63cff6d70ab09237b7718f39615e40ad0828 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.

Others are certain user mode configurations that are currently getting set to values that shouldn't necessarily be dictated by the driver.
