They only affect Samsung SoCs and have only been upstream for half a
year, so I doubt it's heavily used.

This only ever described a small section of the huge set of PMU
registers anyway. Before it described up to three registers
controlling different PHYs (using hardcoded offsets in the code to
later find the right one)... with my patch every PHY's DT entry only
describes the one register concerning itself, which makes more sense
in my opinion. It will also prevent the register descriptions in
different DT entries from overlapping.
