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. -Doug
