I was looking at the DP phy binding in another thread and I'm wondering
what qmp-usb3-uni-phy means. Is that a usb3 phy that doesn't have DP phy
combined with it? It looks like the DP phy binding needs to be merged
with this binding (and some of the driver part too), so I'm not sure
this binding is correct as it stands. Probably needs to be updated to
support DP too.

There's a lot of if-then nesting stuff. Maybe we could split the binding
into many files for the different compatibles so that it is more
readable.

Hi Sandeep,
I fear this needs yet another re-spin since the PHY tree now has commit
0347f0dcbd2f0e ("phy: qcom-qmp: Add MSM8996 UFS QMP support").
