2022-05-12drm/bridge: tc358767: Add DSI-to-(e)DP mode supportMarek Vasut
Implement DSI-to-e(DP) mode, which is a mix of currently supported DSI-to-DPI and DPI-to-(e)DP modes. The input side is configured as either DSI or DPI, the DP AUX channel is registered for both input side options, and the DSI host is attached for both DPI and (e)DP output side options. One notable detail is that the DSI-to-(e)DP mode requires the Pixel PLL to be always enabled, which is not needed for DPI-to-(e)DP mode which gets the matching clock direct from DPI Pixel Clock instead.

2022-05-12drm/bridge: tc358767: Factor out DSI and DPI RX enablementMarek Vasut
Factor out register programming to configure the chip video RX side for reception of video data from DSI or DPI. This is particularly useful in the (e)DP output mode, where the video data can be received from either DPI or DSI. While only the former is supported in (e)DP output mode so far, this patch is added in preparation for addition of the later. There is a change in the order or register programming in case of the DSI-to-DPI mode. The DSI RX side is now programmed and enabled all in one place after the output mode has been configured. Before this change, the DSI RX has been programmed before the output mode has been set and only enabled afterward. The order makes no difference however, since the DSI RX is only enabled at the end either way.

2022-05-12drm/mgag200: Add FB_DAMAGE_CLIPS supportJocelyn Falempe
The driver does support damage clips, but doesn't advertise it. So when running gnome/wayland on Matrox hardware, the full frame is copied to the slow Matrox memory, which leads to very poor performances. Add drm_plane_enable_fb_damage_clips() to advertise this capability to userspace. With this patch, gnome/wayland becomes usable on Matrox GPU.

2022-05-05drm/edid: skip CTA extension scan in drm_edid_to_eld() just for CTA revJani Nikula
The DisplayID CTA data block version does not necessarily match the CTA revision. Simplify by postponing drm_edid_to_eld() slightly, and reusing the CTA revision extracted by drm_parse_cea_ext(). By not bailing out early in drm_edid_to_eld() we may end up filling meaningless data to the ELD. However, the main decision for audio is not the ELD, but rather drm_detect_monitor_audio() called by drivers. (Arguably a future cleanup could do that in drm_add_edid_modes() and cache the result in the connector.)
