Sorry for slow replies. :(

This mostly looks good. Some small things needs fixing:

This is a bool driver, yet it uses MODULE* macros at the end of the file.
Check the recent commits from Paul Gortmaker cleaning this up.
Just a git log -p --author=Gortmaker in the main kernel tree will quickly
give you an idea of what you have to do.

So either the same pins are used for GPIO or PWM.
And this pattern persists.

Do you have a brewing GPIO driver for this block as well?
Is it a separate front-end calling to pinctrl using the
pinctrl_gpio_* calls or do you plan to patch it into this
driver?

This is more of a question.

Apart from this it looks good.
