[PATCH v2 1/8] dt-bindings: nfc: nxp,nci: convert to dtschema

Krzysztof Kozlowski
2021-10-11T07:39:51Z

Convert the NXP NCI NFC controller to DT schema format.

Drop the "clock-frequency" property during conversion because it is a
property of I2C bus controller, not I2C slave device. It was also never
used by the driver.

-Required properties:
-- compatible: Should be "nxp,nxp-nci-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 chip
-
-Optional SoC Specific Properties:
-- pinctrl-names: Contains only one value - "default".
-- pintctrl-0: Specifies the pin control groups used for this controller.
-- firmware-gpios: Output GPIO pin used to enter firmware download mode
