Anyways, fast-forward to this day, I don't see it handling valid_mask. I
think it is a must for this device/driver, where pins can be either
GPIOs or ADC inputs.

Why not just add a .init_valid_mask() to
struct gpio_regmap_config so it can just pass that
down to its gpio_chip?

OK I don't want to load you with too much extra work for
the driver, but it seems such a small thing for a blocker,
and Michael who wrote the library is really helpful
with extending the code, so consider it!
