* 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";
};
