Code also requires a "pm" clock.

Shouldn't be ":", should be "=".

nit: I don't thin it's common to have spaces before/after the ">" and "<".
nit: Be consistent about 0 vs. 0x0 in ranges.

Should be "reg-names" (with an "s")

You have 5 resets but 4 reset names.  That doesn't seem right.  Code
shows you only getting 4, so presumably you need to remove the
SRST_PCIEPHY one.

Thanks for catching these above as I forgot to rework the this sample.
