-
-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.

-Example (for ARM-based BeagleBone with PN544 on I2C2):

Rob,
The netdev folks marked patch as not-applicable, so I guess they expect
you to pick it up.
Can you take it? Similarly to my NFC bindings conversion sent this weekend:
https://lore.kernel.org/linux-nfc/[email protected]/T/#t
Best regards,
Krzysztof

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.
Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

I think clock-frequency should be dropped from I2C slave device.
Similarly to this one:

You have right, it isn't parsed by driver and values match parent i2c
bus. I dropped it in next revision.
