Sending in a bunch of almost-finished (hence RFC) Sony panel drivers upon drm/msm request, to further discussions around DSC panels and DSI pclk calculations. This brings support for the following Sony Xperia devices: - Xperia XZ3 (DSC) - Xperia 1 (DSC) - Xperia 5 - Xperia 10 II (shared with Xperia 5) - Xperia 5 II (DSC, 120Hz) And, since the XZ3 already has all the DT in place to enable the panels on its smaller XZ2(c) siblings, an extra patch is included to add the new compatible string and properties to this device .dts. DTS for other boards/platforms will come later, after cleaning up preliminary patches (e.g. DPU catalog additions, SoC/board DTS for the MDSS subsystem, etc). - File- and compatible names: None of my downstream sources describe the product name of the panels used here; in few cases the Display-IC is known but for the Xperia XZ3 Xperia 1 we have to make-do with a vendor name only. Naming suggestions definitely welcome; i.e. I'm especially not fond of sony-griffin-samsung.c :) - Panels/drivers featuring multiple modes As brought up earlier in #freedreno drm_panel drivers can provide multiple modes, but the selected mode is never communicated back to the panel. This either has to be added to the driver, or the drivers in question have to be converted to drm_bridges (suggestion from #freedreno). That should allow us to select a mode at runtime, and downstream even defines "fast paths" to switch from one mode to the next (e.g. when only adjusting the refresh rate) without powering the panel off and on again, which we can hopefully support too. For now the choice between either mode has been hardcoded behind a static const bool. - DSC Not much to discuss here except that "it works" after piecing together various series on the lists. No dependencies to make this series apply/compile, though. - pclk The brunt of the discussion is around getting these command mode panels functioning at their desired 60Hz or 120Hz refresh rate without tearing/artifacts, and without hacks. Part of that discussion around DSC-specific timing adjustments is happening in [1], but the sofef01 (non-DSC) Driver-IC is also struggling on the Xperia 5 specifically, as outlined in that specific patch. That is currently "addressed" with a "porch hack" but should probably have some sort of overhead / transfer time taken into account in the MSM DSI driver. Let me know what the best place is to collate all the relevant info (links to downstream panel DTS, outcomes with different patches and tweaks, etc). A new fd.o drm/msm issue?
