* Microchip Universal Asynchronous Receiver Transmitter (UART)
Required properties:
- compatible: Should be "microchip,pic32mzda-uart"
- reg: Should contain registers location and length
- interrupts: Should contain interrupt
- clocks: Phandle to the clock.
See: Documentation/devicetree/bindings/clock/clock-bindings.txt
- pinctrl-names: A pinctrl state names "default" must be defined.
- pinctrl-0: Phandle referencing pin configuration of the UART peripheral.
See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
Optional properties:
- cts-gpios: CTS pin for UART
Example:
uart1: serial@1f822000 {
compatible = "microchip,pic32mzda-uart";
reg = <0x1f822000 0x50>;
interrupts = <112 IRQ_TYPE_LEVEL_HIGH>,
<113 IRQ_TYPE_LEVEL_HIGH>,
<114 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&rootclk PB2CLK>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart1
&pinctrl_uart1_cts
&pinctrl_uart1_rts>;
cts-gpios = <&gpio1 15 0>;
};
