[PATCH v6 00/39] i.MX Media Driver

[Steve Longerbeam]

In version 6:

- moved FIM error event back to a i.MX private event. I would like to
  leave this as a (private) event rather than reporting a vb2 queue
  error, for now. If and when the i.MX6 timer input capture patch is
  accepted later, then this event can become a queue error.

- removed new-frame-before-end-of-frame (NFB4EOF) event. Instead when
  this IPU DMA channel error occurs, the next captured frame is marked
  with the vb2 error flag.

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

- ov5640: propagate return codes from the register read/write primitives
  in various places.

- ov5640: removed the [gs]_parm ops.

- ov5640: avoid possible divide-by-0's.

- only the CSI subdevice implements [gs]_frame_interval now (or needs
  to). Those ops have been removed from the subdevices that have no
  control over frame rate.

- removed the patch that adds v4l2_subdev_link_validate_frame_interval().

- properly propagate the TRY formats from sink to source pads within the
  subdevices (spotted by Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>).

- added enum_frame_size op to imx-ic-prpencvf and CSI subdevices.

- added enum_frame_intervals op to CSI subdevice (patch from Russell
  King <rmk+kernel@xxxxxxxxxxxxxxx>).

- added V4L2 interface ops enum_framesizes and enum_frameintervals, which
  calls the corresponding subdev op at the connected source subdev (patch
  from Russell King <rmk+kernel@xxxxxxxxxxxxxxx>).

- added missing Bayer support to CSI subdevice (patch from Russell King
  <rmk+kernel@xxxxxxxxxxxxxxx>).

- switched to v4l2_pipeline_pm_use() and v4l2_pipeline_link_notify()
  for the pipeline power management.

- the power-on order has changed due to above: the sensor now
  is powered on _before_ the MIPI CSI-2 receiver, which means
  MIPI CSI-2 receiver startup sequence steps 3, 4, and 5 can
  be moved up to csi2_s_power() from csi2_s_stream(). And that
  means step 7 (wait for clock lane) now has a place to be called
  in csi2_s_stream().

- changed the bus_info string for the capture device interfaces to
  "platform:[src_sd->name]" instead of using the capture device name,
  so that the bus_info strings are unique between the capture devices.
  I was hoping this would provide unique device node symlink names under
  /dev/v4l/by-path/, but they are still named
  "platform-capture-subsystem-video-indexNN".

- fixed cropping and /2 downsizing in the CSI subdevice. These should be
  specified using the crop and compose APIs at the sink pad, not the
  source pad (patch from Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>).

- added a check at CSI subdevice stream on. If the connected sensor
  reports faulty frames at power on via g_skip_frames op, the CSI
  should avoid capturing those frames before enabling the CSI.

- moved imx.h UAPI header to include/linux/imx-media.h while imx-media
  driver is still under staging.
