Kernel-3.10.0-957.el7_msm_serial

• Qualcomm MSM UART

Required properties:

• compatible :
  • “qcom,msm-uart”, and one of “qcom,msm-hsuart” or
    “qcom,msm-lsuart”.
• reg : offset and length of the register set for the device
  for the hsuart operating in compatible mode, there should be a
  second pair describing the gsbi registers.
• interrupts : should contain the uart interrupt.

There are two different UART blocks used in MSM devices,
“qcom,msm-hsuart” and “qcom,msm-lsuart”. The msm-serial driver is
able to handle both of these, and matches against the “qcom,msm-uart”
as the compatibility.

The registers for the “qcom,msm-hsuart” device need to specify both
register blocks, even for the common driver.

Example:

uart@19c400000 {
    compatible = "qcom,msm-hsuart", "qcom,msm-uart";
    reg = <0x19c40000 0x1000>,
          <0x19c00000 0x1000>;
    interrupts = <195>;
};
