[v20,00/10] SAGV support for Gen12+

Message

For Gen11+ platforms BSpec suggests disabling specific
QGV points separately, depending on bandwidth limitations
and current display configuration. Thus it required adding
a new PCode request for disabling QGV points and some
refactoring of already existing SAGV code.
Also had to refactor intel_can_enable_sagv function,
as current seems to be outdated and using skl specific
workarounds, also not following BSpec for Gen11+.

v17: Had to rebase the whole series.

v19: Added some new patches in between, rebased

v20: Added new patches and rebased the series

Stanislav Lisovskiy (10):
  drm/i915: Start passing latency as parameter
  drm/i915: Eliminate magic numbers "0" and "1" from color plane
  drm/i915: Introduce skl_plane_wm_level accessor.
  drm/i915: Add intel_atomic_get_bw_*_state helpers
  drm/i915: Extract gen specific functions from intel_can_enable_sagv
  drm/i915: Add proper SAGV support for TGL+
  drm/i915: Added required new PCode commands
  drm/i915: Rename bw_state to new_bw_state
  drm/i915: Restrict qgv points which don't have enough bandwidth.
  drm/i915: Enable SAGV support for Gen12
