This series is a split off of the sl28cpld series: https://lore.kernel.org/linux-gpio/20200423174543.17161-1-michael@walle.cc/
I wasn't sure if I should also include the gpiochip_irqchip_add_domain() patch here. So feel free to skip it. OTOH if you use interrupts with gpio-regmap it is quite handy.
For an actual user see the patch 11/16 ("gpio: add support for the sl28cpld GPIO controller") of the series above.
Changes since v3: - set reg_dat_base, that was actually broken - fix typo - fix swapped reg_in_dir/reg_out_dir documentation - use "goto err" in error path in gpio_regmap_register()
Changes since v2: See changelog in the former patch series.
