Thanks for a long letter, took som time to read, but as usual it
contains good stuff!
I think you're talking about two things here:
1) The need to configure per-pin "stuff" like biasing, driving,
load capacitance ... whatever
2) The need to handle state transitions of pinmux settings.

It might be a good place for me to catch up the pinctrl subsystem
discussion, as far as imx migration concerned.
I have not read the backlog of all the previous discussion, so please
excuse me if something I put here have been discussed.

Linus, (and other people interested in pinmux!)
I've started to look at porting the Tegra pinmux driver to your pinctrl
subsystem. In order to replace the existing pinmux driver, I need a way
to support configuring options such as tri-state, pull-up/down, drive-
strength, etc.
At this point, I ha
