linux-toradex.git/drivers/gpio/gpio-moxtet.c, branch v7.0-rc2 Linux kernel for Apalis and Colibri modules treewide: rename GPIO set callbacks back to their original names 2025-08-07T08:07:06+00:00 Bartosz Golaszewski bartosz.golaszewski@linaro.org 2025-07-17T13:21:26+00:00 d9d87d90cc0b10cd56ae353f50b11417e7d21712 The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed.

gpio: Use new GPIO_LINE_DIRECTION 2019-11-07T08:27:48+00:00 Matti Vaittinen matti.vaittinen@fi.rohmeurope.com 2019-11-06T08:54:12+00:00 e42615ec233b30dfaf117b108d4cb49455b4df1d It's hard for occasional GPIO code reader/writer to know if values 0/1 equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT to help them out. NOTE - for gpio-amd-fch and gpio-bd9571mwv: This commit also changes the return value for direction get to equal 1 for direction INPUT. Prior this commit these drivers might have returned some other positive value but 1 for INPUT.
