Subject: [PATCH v6 0/3] gpio: generic regmap implementation
Date: Thu, 28 May 2020 16:58:42 +0200 [thread overview]
Message-ID: <20200528145845.31436-1-michael@walle.cc> (raw)
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 v5:
- add names property
- addressed Alex' remarks:
- moved header from i/l/gpio-regmap.h to i/l/gpio/regmap.h
- fixed kernel doc
- described rules how to use the register base offsets
- missing forward declarations
- style changes
- return -EOPNOTSUPP, in code path we should never reach
- added check to have input and output base regs if there is a direction
register
- added MAINTAINERS patch
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()
