I'm still having some other troubles with the hsi2 (UFS) power domain on gs101,
but I can confirm the usb-phy is part of the hsi0 (USB) power domain. So for the
ufs-phy I presume it's similar: it should be part of the hsi2 power domain. There
certainly is no separate domain for the ufs-phy itself.
See also my reply to the other patch:

Does that answer your question?
Cheers,
Andre'
