Hi Nitin,
>
> GCC_UFS_PHY_GDSC is UFS controller GDSC. For sc7280 Phy we don't need this.
In the current dt-bindings the power-domains property is required.
Is there another power-domain for the PHY to use, or do we need to
adjust the bindings to not require power-domains property for ufs phy on
sc7280?
Also, with "PHY" in the name, it's interesting that this is not for the
phy ;)
