Hi,
I have this in my rpi.dts file:
	spi0 {
		rfid0 {
			compatible = “rfid,mfrc5”;
			spi-chipselect = <0>;
			reset {
				compatible = “pcd-reset”;
				gpios = <&gpio 22 2>;
			};
	};

my mfrc5 driver is starting to work - i can load, open, ioctl, unload,
but after much grepping, I can’t figure out how from inside the driver i can
access the reset pin - which i have defined as gpio 22
ofwdump -aP

# ofwdump -aP
    ...
    Node 0x13c4: spi0
      compatible:
        62 72 6f 61 64 63 6f 6d 2c 62 63 6d 32 38 33 35 2d 73 70 69

      interrupts:

      Node 0x143c: rfid0
        compatible:
          72 66 69 64 2c 6d 66 72 63 35 00 
          'rfid,mfrc5'
        spi-chipselect:
          00 00 00 00 
        Node 0x1470: reset
          compatible:
            70 63 64 2d 72 65 73 65 74 00 
            'pcd-reset'
          gpios:
            00 00 00 03 00 00 00 16 00 00 00 02
