Hello, This changeset adds new V4L2_CID_ALPHA_COMPONENT control that allows to configure an alpha component of all pixels on the video capture device or on capture queue of a mem-to-mem device. This is meant for devices that allow to set a per-pixel alpha at the pipeline output to a desired value and where the input alpha component doesn't influence the output alpha value. The second patch adds the control to s5p-fimc video capture and mem-to-mem driver. This changset also does a minor cleanup at the user controls DocBook chapter. Changes since v2: - rename V4L2_CID_COLOR_ALPHA to V4L2_CID_ALPHA_COMPONENT, - the documentation improvements.
