PN7221 adaptation for Android 16

[zhangkai]

Could you please advise whether "AN14880 PN7160/PN7220 - Android 16 porting guide" is applicable to the PN7221 chip?

If not applicable, please provide the documentation for porting PN7221 to Android 16.

The chip type read by the HAL layer is PN7220, as shown in the following logs:07-01 02:08:17.400 518 5053 D NxpHal : processChipType Setting Default ChiptType pn722007-01 02:08:17.400 518 5053 D NxpHal : processChipType Product : pn722007-01 02:08:17.400 518 5053 D NxpHal : phNxpNciHal_configFeatureList ()chipType = 407-01 02:08:17.400 518 5053 D NxpTml : phTmlNfc_e_setFragmentSize 0x22A

However, the actual silkscreen marking on the chip is PN7221.

Could you advise whether NXP_NFC_HW in device-nfc.mk should be configured as pn7220_i2cs or pn7221_i2cs?
