I don't think I'll have time to look at this week, but I did notice that
you fail do describe the clocks, regulators, and resets (as you also
did for the UFS PHY binding) which are currently different from
sc8280xp.

Please be more careful when adding compatible strings so we get this
right. You should also double check that the differences are really
warranted and not just due the vendor using different names for the same
resource.

At least the reset must be renamed ("pcie_1_nocsr_com_phy_reset", e.g.
drop 'pcie' and 'reset', maybe more).

Hmm, sorry about that. I will double check against the pcie phy nodes I
have for sm8550.

As for the UFS, if your are referring to the following patchset [1], the phy
node looks exactly the same as on sc8280xp, therefore no other binding
update, other than compatible, was needed.

Yes, but I was referring to your original submission which added
different names for the clocks without updating the binding. In that
case, those clocks were really the same ones as the ones on sc8280xp so
it was only the driver and dts changes that were wrong:
