Answering to myself on this point, the registers are properly described
in the iMX8MP reference manual...
I don't make much sense of it at this point (what's SDC..?), but I guess
it does sound likely we could generate the values with some work.

I'll wait for replies a bit first in case one of you understands this
better than I (which is quite likely!), but can give this a few more
hours to help.
