I have MIPI DSI working based on these VOP2 patches. MIPI DSI is currently out of scope for us, I only worked on it up to the point where it works for me on the RK3568 EVB board to be able to test the VOP2 driver. You can get the patches here: https://git.pengutronix.de/cgit/sha/linux/log/?h=rockchip-vop2-mipi The patches are not in a mainline suitable shape, but could well serve as a starting point.
