[Linux-stm32] [PATCH net-next 09/12] gpio: tc956x: add TC956x/QPS615 support

Why doesn't this power controller driver actually use this driver to
control the GPIOs? Chicken/egg?

Maybe add a comment why gpio-regmap.c cannot be used. You probably
need to instantiate it twice, but i still think you will end up with
less code.
