Power-domains need to express their active states in DT and what's better than OPP table for that.
This patch allows power-domains to reuse OPP tables to express their active states. The "opp-hz" property isn't a required property anymore as power-domains may not always use them.
Then maybe you shouldn't be trying to make OPP table work here. At that point you just need a table of voltage(s) per performance state?
Because that's what Kevin strongly recommended in the previous versions.
@Kevin: Would you like to reply here ?
Add a new property "domain-performance-state", which will contain positive integer values to represent performance levels of the power-domains as described in this patch.
Why not reference the OPP entries from the domain:
performance-states = <&opp1>, <&opp2>;
Because that would require additional code in the OPP core to parse these then. Right now it is quite straight forward with the bindings I presented.
Just thinking out loud, not saying that is what you should do. The continual evolution of power (management) domain, idle state, and OPP bindings is getting tiring.
I agree :)
