[PATCH v5 0/2] gpio: generic regmap implementation
From: Michael Walle
Date: Wed May 27 2020 - 23:59:15 EST
This series is a split off of the sl28cpld series:
https://lore.kernel.org/linux-gpio/20200423174543.17161-1-michael@xxxxxxxx/
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.
