2025-02-27dt-bindings: display: panel: Add Raydium RM67200Sebastian Reichel
The Rockchip W552793DBA-V10 display/touchscreen board contains a Wanchanglong W552793BAA panel, which in turn is using a Raydium RM67200 MIPI-DSI controller. Add a DT binding for the DSI panel.

2025-02-25drm/amd/display: stop DML2 from removing pipes based on planesMike Katsnelson
[Why] Transitioning from low to high resolutions at high refresh rates caused grey corruption. During the transition state, there is a period where plane size is based on low resultion state and ODM slices are based on high resoultion state, causing the entire plane to be contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane, causing an underflow since the pixel rate for the higher resolution cannot be supported on one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice with no plane. This is possible to do without negative consequences because pipes can now take the minimum viewport and draw with zero recout size, removing the need to have the pipe turned off. [How] In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by the plane. This prevents the pipes for those ODM slices from being freed.

2025-02-25drm/amd/display: Increase halt timeout for DMCUB to 1sNicholas Kazlauskas
[Why] If we soft reset before halt finishes and there are outstanding memory transactions then the memory interface may produce unexpected results, such as out of order transactions when the firmware next runs. These can manifest as random or unexpected load/store violations. [How] Increase the timeout before soft reset to ensure the DMCUB has quiesced.

2025-02-25drm/amd/display: Update FIXED_VS Link Rate Toggle Workaround UsageMichael Strauss
[WHY] Previously the 128b/132b LTTPR support DPCD field was used to decide if FIXED_VS training sequence required a rate toggle before initiating LT. When running DP2.1 4.9.x.x compliance tests, emulated LTTPRs can report no-128b/132b support which is then forwarded by the FIXED_VS retimer. As a result this test exposes the rate toggle again, erroneously causing failures as certain compliance sinks don't expect this behaviour. [HOW] Add new DPCD register defines/reads to read LTTPR IEEE OUI and device ID. Decide whether to perform the rate toggle based on the LTTPR's IEEE OUI which guarantees that we only perform the toggle on affected retimers.

2025-02-25drm/amd/display: ACPI Re-timer ProgrammingRafal Ostrowski
[Why] We must implement an ACPI re-timer programming interface and notify ACPI driver whenever a PHY transition is about to take place. Because some trace lengths on certain platforms are very long, then a re-timer may need to be programmed whenever a PHY transition takes place. The implementation of this re-timer programming interface will notify ACPI driver that PHY transition is taking place and it will trigger the re-timer as needed. First we need to gather retimer information from ACPI interface. Then, in the PRE case, the re-timer interface needs to be called before we call transmitter ENABLE. In the POST case, it has to be called after we call transmitter DISABLE. [How] Implemented ACPI retimer programming interface.
