Fix up the dbuf bandwidth cdclk calculations to match the spec,
and also implement the cdclk based pipe max bandwidth limit.
TODO: intel_bw contains two orthogonal things (qgv vs. cdclk).
We should probably just split it into two parts to life
less confusing. But as usual naming is hard so I didn't
go for that yet...
v2: Rebased due to the async flip wm0/ddb stuff
Ville Syrjälä (9):
drm/i915: Tweak plane ddb allocation tracking
drm/i915: Split plane data_rate into data_rate+data_rate_y
drm/i915: Pre-calculate plane relative data rate
drm/i915: Remove total[] and uv_total[] from ddb allocation
drm/i915: Nuke intel_bw_calc_min_cdclk()
drm/i915: Round up when calculating display bandwidth requirements
drm/i915: Properly write lock bw_state when it changes
drm/i915: Fix DBUF bandwidth vs. cdclk handling
drm/i915: Add "maximum pipe read bandwidth" checks
