[PATCH v2 0/9] 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.

Changes in v2:
- Make gpio-watchdog depend on OF && GPIOLIB
- Drop picked up patches
- Link to v1: https://patch.msgid.link/20260304-gpio-of-kconfig-v1-0-d597916e79e7@oss.qualcomm.com

[PATCH v2 1/9] arm64: Kconfig: drop unneeded dependency on OF_GPIO

[Bartosz Golaszewski]

OF_GPIO is selected automatically on all OF systems. Any symbols it

explicitly.

[PATCH v2 3/9] 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.

[PATCH v2 9/9] media: i2c: drop unneeded 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. For Kconfig entries that have no other dependencies: convert
it to requiring OF to avoid new symbols popping up for everyone in make
config, for others just drop it altogether.
