Subject: [PATCH v5 0/2] gpio: generic regmap implementation

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 v4:
 - add comment about can_sleep
 - fix config->label typo
 - add config->names property

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.
