Subject: [PATCH v3 04/18] gpiolib: add build option for CDEV v1 ABI
Date: Sun, 9 Aug 2020 21:25:15 +0800 [thread overview]
Message-ID: <20200809132529.264312-5-warthog618@gmail.com> (raw)
In-Reply-To: <20200809132529.264312-1-warthog618@gmail.com>
Add a build option to allow the removal of the CDEV v1 ABI.
Suggested-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Signed-off-by: Kent Gibson <warthog618@gmail.com>

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.
