* 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-bindings.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>;
|
|
};
