[PATCH v7 00/34] i.MX Media Driver

[Steve Longerbeam]

In version 7:

- video-mux: switched to Philipp's latest video-mux driver and updated
  bindings docs, that makes use of the mmio-mux framework.

- mmio-mux: includes Philipp's temporary patch that adds mmio-mux support
  to video-mux driver, until mux framework is merged.

- mmio-mux: updates to device tree from Philipp that define the i.MX6 mux
  devices and modifies the video-mux device to become a consumer of the
  video mmio-mux.

- minor updates to Documentation/media/v4l-drivers/imx.rst.

- ov5640: do nothing if entity stream count is greater than 1 in
  ov5640_s_stream().

- Previous versions of this driver had not tested the ability to enable
  multiple independent streams, for instance enabling multiple output
  pads from the imx6-mipi-csi2 subdevice, or enabling both prpenc and
  prpvf outputs. Marek Vasut tested this support and reported issues
  with it.

  v4l2_pipeline_inherit_controls() used the media graph walk APIs, but
  that walks both sink and source pads, so if there are multiple paths
  enabled to video capture devices, controls would be added to the wrong
  video capture device, and no controls added to the other enabled
  capture devices.

  These issues have been fixed. Control inheritance works correctly now
  even with multiple enabled capture paths, and (for example)
  simultaneous capture from prpenc and prpvf works also, and each with
  independent scaling, CSC, and controls. For example prpenc can be
  capturing with a 90 degree rotation, while prpvf is capturing with
  vertical flip.

  So the v4l2_pipeline_inherit_controls() patch has been dropped. The
  new version of control inheritance could be made generically available,
  but it would be more involved to incorporate it into v4l2-core.

- A new function imx_media_fill_default_mbus_fields() is added to setup
  colorimetry at sink pads, and these are propagated to source pads.

- Ensure that the current sink and source rectangles meet alignment
  restrictions before applying a new rotation control setting in
  prp-enc/vf subdevices.

- Chain the s_stream() subdev calls instead of implementing a custom
  stream on/off function that attempts to call a fixed set of subdevices
  in a pipeline in the correct order. This also simplifies imx6-mipi-csi2
  subdevice, since the correct MIPI CSI-2 startup sequence can be
  enforced completely in s_stream(), and s_power() is no longer
  required. This also paves the way for more arbitrary OF graphs
  external to the i.MX6.

- Converted the v4l2_subdev and media_entity ops structures to const.
