* Universal Asynchronous Receiver/Transmitter (UART)
|
|
- compatible: "rockchip,rk_serial"
|
|
Compatibility with all rk28xx rk29xx rk30xx rk31xx SOCs.
|
|
- reg: The base address of the UART register bank.
|
|
- interrupts: A single interrupt specifier.
|
|
- id: port line, determine the ttySx
|
|
- use-dma-rx: enable dma receive
|
|
- use-dma-tx: enable dma tramsmit
|
|
Example:
|
uart0: serial@10124000 {
|
compatible = "rockchip,rk_serial";
|
reg = <0x10124000 0x100>;
|
interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
|
clock-frequency = <24000000>;
|
id = <0>;
|
use-dma-rx;
|
use-dma-tx;
|
status = "disabled";
|
};
