My plan is to have this driver upstream for 5.10, and getting it out of staging by Kernel 5.11. So, I doubt that the DRM kAPIs would change a lot during those 2 Kernel cycles. In any case, I'm also fine to have a final patch at the end of this series moving it out of staging. The only thing that, IMHO, prevents it to be out of staging is the LDI underflow. Right now, if no input events reach the driver, DPMS will put the monitor to suspend, and it never returns back from life. I bet that, once we discover the root cause, the fix would be just a couple of lines, but identifying where the problem is can take a while.
