1*4882a593Smuzhiyun* MSM Serial UART
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe MSM serial UART hardware is designed for low-speed use cases where a
4*4882a593Smuzhiyundma-engine isn't needed. From a software perspective it's mostly compatible
5*4882a593Smuzhiyunwith the MSM serial UARTDM except that it only supports reading and writing one
6*4882a593Smuzhiyuncharacter at a time.
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunRequired properties:
9*4882a593Smuzhiyun- compatible: Should contain "qcom,msm-uart"
10*4882a593Smuzhiyun- reg: Should contain UART register location and length.
11*4882a593Smuzhiyun- interrupts: Should contain UART interrupt.
12*4882a593Smuzhiyun- clocks: Should contain the core clock.
13*4882a593Smuzhiyun- clock-names: Should be "core".

16*4882a593Smuzhiyun
17*4882a593SmuzhiyunA uart device at 0xa9c00000 with interrupt 11.
