[PATCH 00/14] gpio: remove uneeded Kconfig dependencies on OF_GPIO

[Bartosz Golaszewski]

NOTE: Each patch in this series can be picked up independently into
maintainer trees.

CONFIG_OF_GPIO is a switch that enables the compilation of the gpiolib-of
module. The module itself handles GPIO lookup via the OF-node tree and
is automatically enabled on all OF systems. It does not export any
public symbols to drivers. There is no reason for them to select or
depend on it in Kconfig.

This series removes any such dependencies from Kconfig. If a given entry
has no other dependencies than OF_GPIO - they are converted to OF to
avoid new symbols popping up for everyone in make config.

[PATCH 06/14] gpio: drop unneeded Kconfig dependencies on OF_GPIO

[Bartosz Golaszewski]

OF_GPIO is selected automatically on all OF systems. Any symbols it
controls also provide stubs so there's really no reason to select it
explicitly. Remove all Kconfig dependencies/selects for GPIO drivers.
For those that have no other dependencies: convert it to requiring
CONFIG_OF instead to avoid new symbols popping up in make config.

This is a depends rather than a select, though it's fairly redundant

AI feedback:

  Could this change inadvertently allow the driver to be selected when GPIOLIB
  is disabled?

  In drivers/gpio/Kconfig, OF_GPIO is defined inside the "if GPIOLIB" block,
  so it implicitly depends on GPIOLIB. By changing the dependency directly to
  OF, the GPIOLIB dependency is lost.

  If GPIOLIB is disabled, the driver will still compile because of the stubs
  in include/linux/gpio/consumer.h, but devm_gpiod_get() will unconditionally
  return -ENOSYS, causing the probe to fail. Since the driver's sole purpose
  is to control a watchdog via a GPIO line, should it be prevented from being
  configured without GPIOLIB by using something like:

	depends on OF && GPIOLIB

It has a point. Please update.

Re: [PATCH 10/14] watchdog: convert the Kconfig dependency on OF_GPIO to OF

Actually, that isn't really true.

if GPIOLIB
...
config OF_GPIO
        def_bool y
        depends on OF
        depends on HAS_IOMEM

OF_GPIO also depends on GPIOLIB and HAS_IOMEM. I don't know why it needs
to depend on HAS_IOMEM, but the GPIOLIB dependency is real.

Patch applied to the pinctrl tree!

I'm picking up the ones that were acked and will send a smaller series
