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