   1 * Microchip Universal Asynchronous Receiver Transmitter (UART)
   2
   3 Required properties:
   4 - compatible: Should be "microchip,pic32mzda-uart"
   5 - reg: Should contain registers location and length
   6 - interrupts: Should contain interrupt
   7 - clocks: Phandle to the clock.
   8           See: Documentation/devicetree/bindings/clock/clock-bindings.txt
   9 - pinctrl-names: A pinctrl state names "default" must be defined.
  10 - pinctrl-0: Phandle referencing pin configuration of the UART peripheral.
  11              See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt

  13 Optional properties:
  14 - cts-gpios: CTS pin for UART
