Hi,
This is the fourth version of my series, the second as a proper
patchset. Now sent for the drm-tip (intel-gfx).
The changes comparing to v1 are just addressing Gustavo's comments.
The major changes are:
* Enable/disable the wakelocks on DC5-6 entry and exit instead of on
DMC load and unload;
* Added bspec link to the commit message;
* A bunch of other small changes.
For the complete list of changes and discussions, please look at the
patchset in patchwork: https://patchwork.freedesktop.org/series/128628/
Please review.
Cheers,
Luca.
