RDA Micro UART
Required properties:
- compatible : "rda,8810pl-uart" for RDA8810PL SoCs.
- reg : Offset and length of the register set for the device.
- interrupts : Should contain UART interrupt.
- clocks : Phandle to the input clock.
Example:
uart2: serial@20a90000 {
compatible = "rda,8810pl-uart";
reg = <0x20a90000 0x1000>;
interrupts = <11 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&uart_clk>;
};
