[RFCv3 00/17] Request API, take three

[Alexandre Courbot]

As discussed yesterday, here is a rebase on the media master branch. A
few minor fixes for typos have also slept in, but otherwise this is
equivalent to v2. I expect to have the buffer queueing behavior fixed in
the next version.

Alexandre Courbot (9):
  media: add request API core and UAPI
  media: videobuf2: add support for requests
  media: vb2: add support for requests in QBUF ioctl
  v4l2: add request API support
  videodev2.h: add request_fd field to v4l2_ext_controls
  v4l2-ctrls: support requests in EXT_CTRLS ioctls
  v4l2: document the request API interface
  media: vim2m: add media device
  media: vim2m: add request support

Hans Verkuil (7):
  videodev2.h: Add request_fd field to v4l2_buffer
  v4l2-ctrls: v4l2_ctrl_add_handler: add from_other_dev
  v4l2-ctrls: prepare internal structs for request API
  v4l2-ctrls: add core request API
  v4l2-ctrls: use ref in helper instead of ctrl
  v4l2-ctrls: support g/s_ext_ctrls for requests
  v4l2-ctrls: add v4l2_ctrl_request_setup
