Hi Okan,
thanks for your patch!
First: why is the word "Regulator" in the subject? I don't quite get it.

This commit log is too terse. Write a bit about what this hardware is.

Is it MAX7300, I don't get this, it seems super-confused.

The driver is pretty straight-forward, but I think this can use the generic GPIO_REGMAP helpers in drivers/gpio/gpio-regmap.c check other drivers selecting this helper library for inspiration.
