| 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 | }; |
