0001 * Microchip Universal Asynchronous Receiver Transmitter (UART)
0002
0003 Required properties:
0004 - compatible: Should be "microchip,pic32mzda-uart"
0005 - reg: Should contain registers location and length
0006 - interrupts: Should contain interrupt
0007 - clocks: Phandle to the clock.
0008 See: Documentation/devicetree/bindings/clock/clock-bindings.txt
0009 - pinctrl-names: A pinctrl state names "default" must be defined.
0010 - pinctrl-0: Phandle referencing pin configuration of the UART peripheral.
0011 See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
0012
0013 Optional properties:
0014 - cts-gpios: CTS pin for UART
0015
0016 Example:
0017 uart1: serial@1f822000 {
0018 compatible = "microchip,pic32mzda-uart";
0019 reg = <0x1f822000 0x50>;
0020 interrupts = <112 IRQ_TYPE_LEVEL_HIGH>,
0021 <113 IRQ_TYPE_LEVEL_HIGH>,
0022 <114 IRQ_TYPE_LEVEL_HIGH>;
0023 clocks = <&rootclk PB2CLK>;
0024 pinctrl-names = "default";
0025 pinctrl-0 = <&pinctrl_uart1
0026 &pinctrl_uart1_cts
0027 &pinctrl_uart1_rts>;
0028 cts-gpios = <&gpio1 15 0>;
0029 };
