	help
	  Two pins are usually reserved for NFC in SoCs that implement the
	  NFCT peripheral. This option switches them to normal GPIO mode.
	  HW enabling happens once in the device lifetime, during the first
	  system startup. Disabling this option will not switch back these
	  pins to NFCT mode. Doing this requires UICR erase prior to
	  flashing device using the image which has this option disabled.

	  NFC pins in nRF52 series: P0.09 and P0.10
	  NFC pins in nRF5340: P0.02 and P0.03

	  This option is deprecated, please use devicetree to configure NFCT
	  pins as GPIOS like this:

	  &uicr {
	      nfct-pins-as-gpios;
	  };
