I agree with the "_domains" rename, I think it's an improvement, but
since you're already renaming things, I have to drop my bikeshed: we
have intel_init_power_{well,domains} and
i915_init_power_{well,domains}. IMHO this is really super annoyingly
confusing, because they sound like they do the same thing. I know it's
not your fault, but while you're at it, could you please propose names
to unconfuse this?
i915_init_power_well takes care of initializing the structs and
pointers, while intel_init_power_well is the only one that touches
hardware. A possible suggestion:
- i915_init_power_well becomes intel_init_power_domains (just because
I don't like the "i915_" prefix, since the PM code uses "intel_" for
everything).
- i915_remove_power_well becomes intel_remove_power_domains (to match
the one above)
- intel_init_power_well becomes intel_init_power_domains_hardware or
intel_init_power_wells (since on the HW these things are actually
called "power wells") or intel_init_hw_power_wells (to combine both
suggestions)
Thanks,
Paulo
