| * 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>; |
| }; |
