1* Microchip Universal Asynchronous Receiver Transmitter (UART) 2 3Required 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 12 13Optional properties: 14- cts-gpios: CTS pin for UART 15 16Example: 17 uart1: serial@1f822000 { 18 compatible = "microchip,pic32mzda-uart"; 19 reg = <0x1f822000 0x50>; 20 interrupts = <112 IRQ_TYPE_LEVEL_HIGH>, 21 <113 IRQ_TYPE_LEVEL_HIGH>, 22 <114 IRQ_TYPE_LEVEL_HIGH>; 23 clocks = <&rootclk PB2CLK>; 24 pinctrl-names = "default"; 25 pinctrl-0 = <&pinctrl_uart1 26 &pinctrl_uart1_cts 27 &pinctrl_uart1_rts>; 28 cts-gpios = <&gpio1 15 0>; 29 };
