2020-01-07	v4l2: camera_proxy: Rationalize arguments to format helpers	Laurent Pinchart
	To clarify code, adopt the following rules for format helpers: - All variables representing V4L2 pixel formats shall use uint32_t - All variables representing DRM pixel formats shall use PixelFormat - Functions returning positive values only shall not have a signed return type Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-01-03	v4l2: v4l2_compat: Add V4L2 compatibility layer	Paul Elder
	Add libcamera V4L2 compatibility layer. This initial implementation supports the minimal set of V4L2 operations, which allows getting, setting, and enumerating formats, and streaming frames from a video device. Some data about the wrapped V4L2 video device are hardcoded. Add a build option named 'v4l2' and adjust the build system to selectively compile the V4L2 compatibility layer. For now we match the V4L2 device node to a libcamera camera based on a devnum that a pipeline handler may optionally map to a libcamera camera.
