Suggested-by: Bartosz Golaszewski Signed-off-by: Kent Gibson --- This patch is before the v2 implementation, and is non-functional until that patch, as some parts of that patch would be written slightly differently if removing v1 was not considered. Adding this patch after that would necessitate revisiting the v2 changes, so this ordering results in two simpler patches. drivers/gpio/Kconfig | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/drivers/gpio/Kconfig b/drivers/gpio/Kconfig index 8e409b9c33dc..0c62e35cf3a6 100644 --- a/drivers/gpio/Kconfig +++ b/drivers/gpio/Kconfig @@ -82,6 +82,18 @@ config GPIO_CDEV If unsure, say Y. +config GPIO_CDEV_V1 + bool "Support GPIO ABI Version 1" + default y + depends on GPIO_CDEV + help + Say Y here to support version 1 of the GPIO CDEV ABI. + + This ABI version is deprecated and will be removed in the future. + Please use the latest ABI for new developments. + + If unsure, say Y. + config GPIO_GENERIC depends on HAS_IOMEM # Only for IOMEM drivers tristate -- 2.28.0
