-* NXP Semiconductors PN544 NFC Controller
-
-Required properties:
-- compatible: Should be "nxp,pn544-i2c".
-- clock-frequency: I²C work frequency.
-- reg: address on the bus
-- interrupts: GPIO interrupt to which the chip is connected
-- enable-gpios: Output GPIO pin used for enabling/disabling the PN544
-- firmware-gpios: Output GPIO pin used to enter firmware download mode
-
-Optional SoC Specific Properties:
-- pinctrl-names: Contains only one value - "default".
-- pintctrl-0: Specifies the pin control groups used for this controller.

I wasn't specific, because pinctrl always go together - names with -0.
This as well should be dropped.
