concerning it I would appreciate if you can review/comment the v2 of SM8650
CAMSS dt bindings I've just sent recently [1], the equivalent property names on
that platform were named "vdda-csiXY-0p9-supply" for VDD_A_CSI_X_Y_0P9 pin.

I believe both these platforms and likely the following ones should provide
similar properties, thus it makes sense to discuss it at the same time.
