From a99cc66807d6c854a7f65f962766c530c91be149 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 7 Feb 2023 16:29:47 +0200 Subject: gpiolib: split of_mm_gpio_chip out of linux/of_gpio.h This is a rarely used feature that has nothing to do with the client-side of_gpio.h. Split it out with a separate header file and Kconfig option so it can be removed on its own timeline aside from removing the of_gpio consumer interfaces.
