1	* Qualcomm MSM UART
2	
3	Required properties:
4	- compatible :
5		- "qcom,msm-uart", and one of "qcom,msm-hsuart" or
6		  "qcom,msm-lsuart".
7	- reg : offset and length of the register set for the device
8		for the hsuart operating in compatible mode, there should be a
9		second pair describing the gsbi registers.
10	- interrupts : should contain the uart interrupt.
11	
12	There are two different UART blocks used in MSM devices,
13	"qcom,msm-hsuart" and "qcom,msm-lsuart".  The msm-serial driver is
14	able to handle both of these, and matches against the "qcom,msm-uart"
15	as the compatibility.
16	
17	The registers for the "qcom,msm-hsuart" device need to specify both
18	register blocks, even for the common driver.
19	
20	Example:
21	
22		uart@19c400000 {
23			compatible = "qcom,msm-hsuart", "qcom,msm-uart";
24			reg = <0x19c40000 0x1000>,
25			      <0x19c00000 0x1000>;
26			interrupts = <195>;
27		};
