Is this going to be sufficient vs. operating-points-v2? Or should it be
a power domain with OPPs?
In principle, switching to operating-points-v2 should be very
straightforward. I have smoke-tested the driver with an
operating-points-v2 table and a phandle to it inside the gpu node
in place of operating-points and it seems to be working fine. At
least it parsed the OPPs and got initialised correctly.
My understanding is that operating-points (v1) are not deprecated
so we could keep the bindings as-is, but please let me know
otherwise and I can try to address that in my next patch version.
In the documentation, it should only be the case of replacing
operating-points with operating-points-v2.
While the opp bindings documentation doesn't mention anything
about operating-points being deprecated, the code and comments in
of.c are pretty clear about this:
/*
* OPPs have two version of bindings now. The older one is deprecated,
* try for the new binding first.
*/
So I shall use operating-points-v2 in my patch v4.
Thanks,
Guillaume
