Where's the corresponding binding update?

Don't you have a dedicated ref clk? In any case, ref_clk_src should not
be here (either rename it 'ref' or replace it).

As for UFS and PCIe these PHY nodes should be updated to use the new
binding scheme which drops the child node and individual register
descriptions (cf. sc8280xp).
