* MSM Serial UART
|
|
|
|
The MSM serial UART hardware is designed for low-speed use cases where a
|
|
dma-engine isn't needed. From a software perspective it's mostly compatible
|
|
with the MSM serial UARTDM except that it only supports reading and writing one
|
|
character at a time.
|
|
|
|
Required properties:
|
|
- compatible: Should contain "qcom,msm-uart"
|
|
- reg: Should contain UART register location and length.
|
|
- interrupts: Should contain UART interrupt.
|
|
- clocks: Should contain the core clock.
|
|
- clock-names: Should be "core".
|
|
|
|
Example:
|
|
|
|
A uart device at 0xa9c00000 with interrupt 11.
|
|
|
|
serial@a9c00000 {
|
|
compatible = "qcom,msm-uart";
|
|
reg = <0xa9c00000 0x1000>;
|
|
interrupts = <11>;
|
|
clocks = <&uart_cxc>;
|
|
clock-names = "core";
|
|
};
