2021-09-20drm/i915/dg2: configure TRANS_DP2_VFREQ{HIGH,LOW} for 128b/132bJani Nikula

2021-09-20drm/i915/dg2: use 128b/132b transcoder DDI modeJani Nikula
128b/132b has a separate transcoder DDI mode, which also requires the MST transport select to be set. Note that we'll use DP MST also for single-stream 128b/132b. Having the FDI and 128b/132b modes share the register mode value complicates things a bit. v2: - Use HAS_DP20 abstraction for 128b/132b mode (Ville) - Use intel_dp_is_uhbr() helper Bspec: 50493 Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/279bfbd979e0256fae13a5231e07e2f4fb665c07.1631191763.git.jani.nikula@intel.com

2021-09-17drm/i915/display/psr: Use drm damage helpers to calculate plane damaged areaJosé Roberto de Souza
drm_atomic_helper_damage_iter_init() + drm_atomic_for_each_plane_damage() returns the full plane area in case no damaged area was set by userspace or it was discarted by driver. This is important to fix the rendering of userspace applications that does frontbuffer rendering and notify driver about dirty areas but do not set any dirty clips. With this we don't need to worry about to check and mark the whole area as damaged in page flips. Another important change here is the move of drm_atomic_add_affected_planes() call, it needs to called late otherwise the area of all the planes would be added to pipe_clip and not saving power.

PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder. Bigjoiner is making life even more confusing by introducing a N:1 relationship between pipes and transcoders. In that case we only enable/configure the transcoder corresponding to the master pipe. Let's do some renames to make it clear we're dealing with the transcoder rather than pipe when it comes to PIPECONF/TRANSCONF. I decided to leave the _cpu_ part out from the function/macro names since the PCH transcoder related stuff already has a _pch_ in their name. So shouldn't be possible to confuse them.

2021-09-14drm/edid: parse the DisplayID v2.0 VESA vendor block for MSOJani Nikula
The VESA Organization Vendor-Specific Data Block, defined in VESA DisplayID Standard v2.0, specifies the eDP Multi-SST Operation (MSO) stream count and segment pixel overlap. DisplayID v1.3 has Appendix B: DisplayID as an EDID Extension, describing how DisplayID sections may be embedded in EDID extension blocks. DisplayID v2.0 does not have such a section, perhaps implying that DisplayID v2.0 data should not be included in EDID extensions, but rather in a "pure" DisplayID structure at its own DDC address pair A4h/A5h, as described in VESA E-DDC Standard v1.3 chapter 3. However, in practice, displays out in the field have embedded DisplayID v2.0 data blocks in EDID extensions, including, in particular, some eDP MSO displays, where a pure DisplayID structure is not available at all. Parse the MSO data from the DisplayID data block.
