    Subject[PATCH v3] dt-bindings: net: nfc: nxp,pn544: Convert txt bindings to yaml
    Date
    Convert bindings for NXP PN544 NFC driver to YAML syntax.

    Signed-off-by: David Heidelberg <david@ixit.cz>
    ---
    v2
    - Krzysztof is a maintainer
    - pintctrl dropped
    - 4 space indent for example
    - nfc node name
    v3
    - remove whole pinctrl

    -
    -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.
