[PATCH 0/6] drm/i915/display: DMC wakelock implementation

[Luca Coelho]

Hi,

This is the third version of my series, now not as an RFC anymore, but
as a proper patchset.

This is what changed compared to RFC v2:

  * Renamed intel_wakelock.[ch] to intel_dmc_wl.[ch]
  * Renamed all functions to match the new file name, intel_dmc_wl_*()
  * Removed the excessive logging
  * Added comment about other CTL registers
  * Changed DMC_WAKELOCK_CFG_ENABLE to DMC_WAKELOCK_CTL_REQ for the
    control registers
  * Add disable function
  * Add module parameter
  * Moved the init to DMC load and added disable

This is one item I promised to look into, but didn't derive into any
code changes:

  * No need to bail out on refcount == 0 in the work handler


Please review.

Cheers,
Luca.
