Sibi might be working on doing that for the SDM845 CPUfreq driver.
Georgi could also change his GPU driver use case to use this BW OPP
table and required-opps.
The problem is that people don't want to start using this until we
decide on the DT representation. So it's like a chicken and egg
situation.
Yeah, I agree to that.
@Georgi and @Sibi: This is your chance to speak up about the proposal
from Saravana and if you find anything wrong with them. And specially
that it is mostly about interconnects here, I would like to have an
explicit Ack from Georgi on this.
And if you guys are all okay about this then please at least commit
that you will convert your stuff based on this in coming days.
I've been using both Saravana's and Georgi's series for a while
now to scale DDR and L3 on SDM845. There is currently no consensus
as to where the votes are to be actuated from, hence couldn't post
anything out.

Thanks Sibi! You might want to convert your patches so that until the
passive governor is ready, you just look up the required opps and vote
for BW directly from the cpufreq driver. Once devfreq governor is
ready, you can switch to it.
Sure I'll do that.
