Hi Here's a second version of this patch set. The only difference is in the second of the two patches which updates the documentation (and therefore also the semantics of the controls) according to people's suggestions, so thanks for those! The controls are now necessarily linear, with a default unity gain. I also went with the approach of documenting the first 3 controls as "refer to the final one", so as to be less repetitive. If anyone has any ideas to improve the formatting, that would of course be great! Thanks again and best regards David David Plowman (2): media: v4l2-ctrls: Add V4L2_CID_NOTIFY_GAIN_XXX controls media: v4l2-ctrls: Document V4L2_CID_NOTIFY_GAIN_XXX controls .../media/v4l/ext-ctrls-image-source.rst | 25 +++++++++++++++++++ drivers/media/v4l2-core/v4l2-ctrls.c | 4 +++ include/uapi/linux/v4l2-controls.h | 4 +++ 3 files changed, 33 insertions(+) -- 2.17.1
