Is there a repo where it has been rebased to v5.8-rc1 (and tested)? Our Pyra MIPI/DSI omap5 panel setup is broken by upstream changes since v5.7-rc1 and I am not sure if it is better to search in the old omapdrm code what is missing now. Or to wait for your DSI code and just update/fix our panel driver (and have a chance to get that one upstream).
