Subject: drm/i915: Move dsc/joiner enable into hsw_crtc_enable()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: bc1ce503769c51c1c06f5ed126b07a545996d697
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Lift the dsc/joiner enable up from the wonky places where it
currently sits (ddi .pre_enable() or icl_ddi_bigjoiner_pre_enable())
into hsw_crtc_enable() where we write the other per-pipe stuff
as well. Makes the transcoder vs. pipe split less confusing.
For DSI this results in slight reordering between the dsc/joiner
enable vs. transcoder timings setup, but I can't really think
why that should cause any issues since the transcoder isn't yet
enabled at that point.
v2: Take care of dsi (Jani)
