Picked for V4, thank you !
How would you determine the values to be set here? I suspect it's the value from register DP0_SnkLTChReq (0x6d4) after link training. Are they dependent on the actual display to be attached?
In my case, I only did trial-and-error, because the test hardware I have available right now ... well, it is a test hardware and won't work reliably with pre-emphasis 0, so I had to up it a bit.
