* 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>;
|
||
|
|
};
