Changes for v5:
            -Fixed some minor comments.
Not a useful changelog. The point of these comments is to remind the
reviewers of what they commented on.
Ok will take care from next version onwards...

 Required properties:
-- compatible : should be "cdns,uart-r1p8", or "xlnx,xuartps"
+- compatible :
+  Use "cdns,uart-r1p8", or "xlnx,xuartps" for Zynq-7xxx SoC.
This is still not right. It was wrong before, but you are touching it so make it
right.

OR doesn't match the dts files. It is AND and the opposite order.

xlnx,xuartps wasn't the best naming, but it's in use so we'll have to live with it
for zynq-7xxx.

+  Use "cdns,uart-r1p12" for Zynq Ultrascale+ MPSoC.
What I meant here was this should have something like "xlnx,mpsoc-uart"
as the first compatible with "cdns,uart-r1p12" as the second. Not sure if
"mpsoc" is the best name here.
You mean something like below
 Use "xlnx,xuartps" or "cdns,uart-r1p8" for Zynq-7xxx SoC.
As I said, it is not an OR condition. 'Use "xlnx,xuartps",
"cdns,uart-r1p8" for Zynq-7xxx SoC
Use "xlnx,zynqmp-uart" or " cdns,uart-r1p12" for Zynq Ultrascale+ MPSoC.
Yes, but as above.

Rob
