Yeah I know...

If you mean that you fix the i.MX driver for all the combines i.MX variants
then I agree.

If you mean to do stuff like allow the code to continue even if the pinmux
isn't found - no. That is not the way we proceed with clocks and
regulators as Mark has taught me recently, so for consistency we
need to error out if no pinmux is found.
