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.
