Does this mean you are working on mainline drivers for these? If you don't mind me asking, what state are these in? Is DSIM being worked on? I am asking these, because I am also working on some drivers for DPP, DECON, and DSIM on the Exynos7885. Now, my DPP and DECON drivers are not even close to complete, they just have the bare minimum for output and vsync, using them as initialized by the bootloader, but I do have a semi-functional DSIM driver (well, existing mainline DSIM driver patched up to work on 7885) that is enough for controlling the DSI panel attached to my phone. If you are working on DPP and DECON drivers, I won't spend much time with those for now, as your driver for ExynosAutoV9 may help a lot with 7885 as well. If you are not working on a DSIM driver, I'll keep working on it for 7885. If you are, I'll have to think about how to move forward. Best regards, David
