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
12
13 Optional properties:
14 - cts-gpios: CTS pin for UART
15
16 Example:
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 };
