This series adds initial support for Xe3p_LPD, Intel's display architecture with IP version 35.
This series contains basic enabling patches and does not provide complete support for the display IP yet. More involved features, like the new PHY implementation and ALPM are implemented as separate patch series. Signed-off-by: Gustavo Sousa <[email protected]> --- Changes in v4: - Skipped patches from v3 that were already applied. - Dropped patch "drm/i915/xe3p_lpd: Enable system caching for FBC" with the expectation that its next version will be sent as a standalone patch. - Link to v3: https://patch.msgid.link/[email protected] Changes in v3: - Reshuffled patches so that most of the ones already containing a r-b are placed at the start. - Dropped "drm/i915/xe3p_lpd: Wait for AUX channel power status", as a similar patch was already applied from a patch series dedicated to LT PHY (https://lore.kernel.org/all/[email protected]/). - Dropped patches related to UINT16 plane formats, as they were incomplete and were not specific to Xe3p_LPD. - Dropped FBC related patches, as Vinod is handling them as a separated series (https://lore.kernel.org/intel-gfx/[email protected]/) - Dropped "drm/i915/xe3p_lpd: PSR SU minimum lines is 4", since that change is not valid according to Bspec. - Incorporated review feedback on the other patches. Please check the changelog in the individual patches for details. - Link to v2: https://lore.kernel.org/r/[email protected] Changes in v2: - Incorporated review feedback.
