Similarly rename the other related functions in the power domain interface. Higher level driver code calling these functions knows only about power domains, not the underlying power wells which may be different on different platforms. Also these functions really init/cleanup/resume power domains and only through that all related power wells, so rename them accordingly. Note that I left i915_{request,release}_power_well as is, since that really changes the state only of a single power well (and is HSW specific). It should also get a better name once we make it more generic by controlling things through a new audio power domain. v4: - use intel prefix instead of i915 everywhere (Paulo) - use a $prefix_$block_$action format (Daniel) Signed-off-by: NImre Deak <imre.deak@intel.com> Reviewed-by: NPaulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

The only real need for this field was in i915_{request,release}_power_well, but there we can get at it by a container_of magic. Also since in the future we'll have multiple power wells each with its own power_well struct it makes sense to remove the field from there where it'd be just redundancy.

Currently we make sure that all power domains are enabled during driver init and turn off unneded ones only after the first modeset. Similarly during suspend we enable all power domains, which will remain on through the following resume until the first modeset. This logic is supported by intel_set_power_well() in the power domain framework. It would be nice to simplify the API, so that we only have get/put functions and make it more explicit on the higher level how this "power well on during init" logic works. This will make it also easier if in the future we want to shorten the time the power wells are on. For this add a new device private flag tracking whether we have the power wells on because of init/suspend and use only intel_display_power_get()/put(). As nothing else uses intel_set_power_well() we can remove it. This also fixes commit 6efdf354 Author: Imre Deak <imre.deak@intel.com> Date: Wed Oct 16 17:25:52 2013 +0300 drm/i915: enable only the needed power domains during modeset where removing intel_set_power_well() resulted in not releasing the reference on the power well that was taken during init and thus leaving the power well on all the time.

In the future we'll need to support multiple power wells, so prepare for that here. Create a new power domains struct which contains all power domain/well specific fields. Since we'll have one lock protecting all power wells, move power_well->lock to the new struct too. No functional change.

So far the modeset code enabled all power domains if it needed any. It wasn't a problem since HW generations so far only had one always-on power well and one dynamic power well that can be enabled/disabled. For domains powered by always-on power wells (panel fitter on pipe A and the eDP transcoder) we didn't do anything, for all other domains we just enabled the single dynamic power well. Future HW generations will change this, as they add multiple dynamic power wells. Support for these will be added later, this patch prepares for those by making sure we only enable the required domains. Note that after this change on HSW we'll enable all power domains even if it was the domain for the panel fitter on pipe A or the eDP transcoder. This isn't a problem since the power domain framework already checks if the domain is on an always-on power well and doesn't do anything in this case.

There is no hard need for this to be a spin lock, as we don't take these locks in irq context from anywhere.
