I'd like to propose myself as co-maintainer of the DRM bridge subsystem if everybody agrees, following the excellent work Laurent and Andrzej did. I have a very little knowledge of DSI, & other bridge drivers, but I'll do my best. For the dw-hdmi driver, we have a big roadmap including : - HDR (this patchset) - HDCP 1/2 - YUV420, YUV422, YUV44, 10bit/12bit/16bit HDMI output - Enhanced audio support and ELD notification to ASoC ... Having a more active maintainer/reviewer team would be needed, at least for the dw-hdmi bridge. I'll also propose Jonas Karlman <jonas@xxxxxxxxx> as reviewer since he is very active for the multimedia support on RockChip, Allwinner and Amlogic SoCs. I'll also propose Jernej Skrabec@xxxxxxxx <jernej.skrabec@xxxxxxxx>, if he wants, as reviewer since he is very active on the Allwinner SoCs side.
