[RFC v2 0/5] drm/i915/display: DMC wakelock implementation

[Luca Coelho]

Hi,

This is the second version of my RFC with this implementation.  What
changed from v1 is that I added a few more patches adding the
implementation in other helper functions.

This is still a bit rough.  Ignore all the traces I added (I'll remove
them).  I'm also planning to add debugfs entries to expose the
wakelock status and control it when testing.  And I'll also add an
option to enable/disable the feature at some point.

Please review.

Cheers,
Luca.
