Is TITAN_TOP a part of the MMCX or CX domain? In the former case,
please drop separate mmcx vote here and let it come through the
titan_top (it might require camcc driver and node modifications).

The change was requested by Brian, most likely in connection with
upcoming migrations. I think he would be able to explain the exact
reasons. As far as the facts are concerned, this is not currently
necessary for the driver to be functional.
In the documentation we have this jpeg block need only TITAN_TOP_GDSC power domain.
However Bryan request to ad MMCX and MX.
As i can see same is for csiphy. Maybe is better to sync with Bryan.

Check hamoa - I believe it is the case there's a separate vote required for MMCX/MXA.

I'm prefectly fine if all that is required on kona is titan_top_gdsc but, basically I'm asking _you_ to go verify the difference and come back with an answer.

"Not required for Kona we checked" - its not about being asked its about checking what's actually required, I'm highlighting this because sm8550 perhaps and hamoa definitely are different.

All of this is in the power-tree documentation. Please find the place where the power-rails are stipulated for venus/iris and then check to see what's required for the titan block and represent all of the necessary rails in the jpeg@{} such that jpeg@{} can run standalone without any of the rest of the block switched on.

I'll trust your diligence in that.
