You should be able to get an idea how to achieve that for example by checking how we did it for UCSI: drivers/usb/typec/ucsi/displayport.c I think you should start by first only registering the alternate mode without any control. That way you should not need to deal with anything else except the DP SID Status register. After that we can add control as the next step. If you need more help, let me know. Br, -- heikki
