drm/i915: Support pf CRC source on haswell transcoder edp
The always-on power well pixel path on haswell is routed such that it bypasses the panel fitter when we use is. Which means the pfit CRC source won't work in that configuration. Add a new disallow-bypass flags to the pfit pipe config state and set it when we want to use the pf CRC. Results in a bit of flicker, but should get the job done. We'll also undo do it afterwards to make sure other tests arent' negatively affected. Totally untested due to lack of hsw laptops around here. v2: s/disallow_bypass/force_power_well_on/ to avoid a double negative (Damien). v3: force_thru because roadsigns. v4: Don't forget the power wells! Also note that until the runtime pm for DPMS series is fully merged the simple disable/enable trick won't work since the ->crtc_mode_set callback is still required to do nasty things. This stuff is tricky, but I think by both fixing up get_crtc_power_domains and the debugfs wa code we should always grab/drop the additional power well correctly. v5: Wrap in () as suggested by Damien to avoid setting reserved values for the edp transcoder path on bdw+ References: https://bugs.freedesktop.org/show_bug.cgi?id=72864 Cc: Damien Lespiau <damien.lespiau@intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Tested-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
