[media] v4l: add videobuf2 Video for Linux 2 driver framework
Videobuf2 is a Video for Linux 2 API-compatible driver framework for multimedia devices. It acts as an intermediate layer between userspace applications and device drivers. It also provides low-level, modular memory management functions for drivers. Videobuf2 eases driver development, reduces drivers' code size and aids in proper and consistent implementation of V4L2 API in drivers. Videobuf2 memory management backend is fully modular. This allows custom memory management routines for devices and platforms with non-standard memory management requirements to be plugged in, without changing the high-level buffer management functions and API. The framework provides: - implementations of streaming I/O V4L2 ioctls and file operations - high-level video buffer, video queue and state management functions - video buffer memory allocation and management Signed-off-by: Pawel Osciak <p.osciak@samsung.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> CC: Pawel Osciak <pawel@osciak.com> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
