2025-02-05drm/i915/display: convert intel_ddi_buf_trans.c to struct intel_displayJani Nikula
Going forward, struct intel_display is the main device data structure for display. Switch to it. For MISSING_CASE(), log the PCI ID instead of the platform to get rid of the i915_drv.h dependency.

The PHY is either c10 or c20, there's no need to check at runtime and complicate the conditions in mtl_get_cx0_buf_trans(). While at it, replace the direct port clock check with intel_dp_is_uhbr().

2022-05-27drm/i915/bios: Split VBT data into per-panel vs. global partsVille Syrjälä
Move the panel specific VBT parsing to happen during the output probing stage. Needs to be done because the VBT parsing will need to look at the EDID to determine the correct panel_type on some machines. We split the parsed VBT data (i915->vbt) along the same boundary. For the moment we just hoist all the panel specific stuff into connector->panel.vbt since that seems like the most convenient place for eg. the backlight code. Note that we simply drop the drrs type check from intel_drrs_frontbuffer_update() since that operates on the whole device rather than a specific connector/encoder. But the check was just a micro optimization so removing it doesn't actually mattter for correctness. TODO: Lot's of cleanup to be done in the future. Eg. most of the DSI stuff could probably be eliminated entirely and just parsed on demand during DSI init. v2: Note the intel_drrs_frontbuffer_update() change Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220510104242.6099-13-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

2022-02-23drm/i915/tgl: Simply subplatform detectionJosé Roberto de Souza
In the past we had a need to differentiate TGL U and TGL Y, there was a different voltage swing table for each subplatform and some PCI ids of this subplatforms are shared but it turned out that it was a specification mistake and the voltage swing table was indeed the same but we went ahead with that patch because we needed to differentiate TGL U and Y from TGL H and by that time TGL H was embargoed so that was the perfect way to land it upstream. Now the embargo for TGL H is long past and now we even have INTEL_TGL_12_GT1_IDS with all TGL H ids, so we can drop this PCI root check and only rely in the PCI ids to differentiate TGL U and Y from TGL H that actually has code differences. Besides the simplification this will fix issues in virtualization environments where the PCI root is virtualized and don't have the same id as actual hardware. v2: - add and set INTEL_SUBPLATFORM_UY Cc: Fred Gao <fred.gao@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Tested-by: Yu He <yu.he@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220222141424.35165-1-jose.souza@intel.com
