-* 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@...00000 {
-	compatible = "qcom,msm-uart";
-	reg = <0xa9c00000 0x1000>;
-	interrupts = <11>;
-	clocks = <&uart_cxc>;
-	clock-names = "core";
-};
