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

Posted by Bartosz Golaszewski 1 month, 1 week ago

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.

I'm picking up the ones that were acked and will send a smaller series
addressing the issue pointed out by Guenter.
