Many thanks for cleaning this up!
I checked that this indeed just renames the pwrseq node names and the
clock node names. I can confirm that the clock names didn't change, also
the SDIO pwrseq still worked as before: boot tested on a BananaPi-M64,
which is affected by both changes.
Also the other changes look fine: the RTL8189 node names and CPU trip
point node names. So:
