Kernel-4.18.0-80.el8_microchip,pic32-uart

• 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>;
};
