description:
  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.

properties:
  compatible:
    const: qcom,msm-uart
