This series adds support for two new values for dmc_wl_enable for
debugging purposes:

  * 2 to mean "match any register", which makes the wakelock to be taken
    for every display MMIO transaction;
  * 3 to mean "always locked", which causes the lock to be taken as soon
    as the DMC wakelock mechanism is enabled and is kept locked until it
    is disabled.

Gustavo Sousa (4):
  drm/i915/dmc_wl: Use enum values for enable_dmc_wl
  drm/i915/dmc_wl: Show description string for enable_dmc_wl
  drm/i915/dmc_wl: Allow enable_dmc_wl=2 to mean "match any register"
  drm/i915/dmc_wl: Allow enable_dmc_wl=3 to mean "always locked"
