Message-ID: <20241024192758.91748-1-brgl@bgdev.pl> Date: Thu, 24 Oct 2024 21:27:57 +0200 From: Bartosz Golaszewski <brgl@...ev.pl> To: Linus Walleij <linus.walleij@...aro.org> Cc: linux-gpio@...r.kernel.org, linux-kernel@...r.kernel.org, Bartosz Golaszewski <bartosz.golaszewski@...aro.org> Subject: [PATCH] gpio: relax the Kconfig dependency on OF_GPIO in drivers From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org> None of the symbols exported in gpiolib-of.h are used by any of the GPIO drivers we maintain. Even if they were, there are stubs for !OF_GPIO. There's no reason for any of the drivers to depend at build-time on GPIO_OF. We can drop all such cases.
