Not a useful changelog. The point of these comments is to remind the 
reviewers of what they commented on.

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.

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.
