This is the third iteration of the Congatec Board Controller series.
There are only few changes for the GPIO driver (commit message, Kconfig,
remove useless cast).
I also rebased the series on Linux v6.12-rc1.
Best Regards,
Thomas

Changes in v3:
- Rebased on Linux v6.12-rc1.
- gpio: improve commit message.
- gpio: in Kconfig move driver definition in the MFD GPIO drivers submenu.
- gpio: remove useless cast.
- gpio: take Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
- i2c: take Acked-by: Andi Shyti <andi.shyti@kernel.org>
- watchdog: take Acked-by: Guenter Roeck <linux@roeck-us.net>
- Link to v2: https://lore.kernel.org/r/20240503-congatec-board-controller-v2-0-681511a01c8f@bootlin.com
Changes in v2:
- mfd: use platform_device_register_simple(), so struct cgbc_platform_data
and cgbc_create_platform_device() were removed.
- mfd: rename cgbc_detect_device() to cgbc_wait_device().
- mfd: remove the useless abstracted function cgbc_command().
- mfd: set the release session message as warning instead of error.
- mfd: minor fixes (sort includes, add comments, fix some alignments and
nit ...).
- gpio: use scoped_guard() and guard().
- gpio: use devm_mutex_init().
- i2c: unset the I2C_FUNC_SMBUS_QUICK flag as smbus quick accesses are not
supported by the controller.
- i2c: rephrase comment for read_maxtime_us.
- i2c: set the invalid frequency message as an info (previously a warning).
- i2c: other minor fixes (sort includes, fix name of i2c_state enum).
- watchdog: add missing includes.
- watchdog: remove warning for the pretimeout.
- watchdog: remove timeout_action and pretimeout_action (ACTION_RESET and
ACTION_SMI are directly used in cgbc_wdt_start()).
- watchdog: set max_timeout and min_timeout.
- watchdog: use watchdog_init_timeout() to set the timeout.
