Thank you for this work! It was indeed interesting reading.
And since your series is targetting some exiting use cases, I would
drop as well academic variants of brain-damaged hw design, I think it
worth to go.
WRT patches,
Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com>
for patches 1-2
and FWIW for patches 3-4.
For the individual drivers I can't say much, code looks good, but I
dunno if it's correct or not.
