87c6f1b57f media: rcar-csi2: Handle per-SoC number of channels
The R-Car CSI-2 interface has a number of selectable 'channels' that
provides pixel data to the VINs during image acquisition.

Each channel can be used to match a CSI-2 data type and a CSI-2 virtual
channel to be routed to output path.

Different SoCs have different number of channels, with R-Car E3 being the
notable exception supporting only 2 of them.

c3d996fb03 media: coda: limit queueing into internal bitstream buffer
The ringbuffer used to hold the bitstream is very conservatively sized,
as keyframes can get very large and still need to fit into this buffer.
This means that the buffer is way oversized for the average stream to
the extend that it will hold a few hundred frames when the video data
is compressing well.

The current strategy of queueing as much bitstream data as possible
leads to large delays when draining the decoder. In order to keep the
drain latency to a reasonable bound, try to only queue a full reorder
window of buffers. We can't always hit this low target for very well
compressible video data, as we might end up with less than the minimum
amount of data that needs to be available to the bitstream prefetcher,
so we must take this into account and allow more buffers to be queued
in this case.

51407c2da0 media: coda: always hold back decoder jobs until we have enough bitstream payload
The bitstream prefetch unit reads data in 256 byte blocks with some kind
of queueing. For the decoder to see data up to a desired position in the
next run, the bitstream has to be filled for 2 256 byte blocks past that
position aligned up to the next 256 byte boundary.
This should make sure we never run into a buffer underrun condition if
userspace does not supply new input buffers fast enough.

30efae3d78 media: omap3isp: Unregister media device as first
While there are issues related to object lifetime management, unregister the
media device first when the driver is being unbound. This is slightly
safer.

ef86eaf97a media: Rename vb2_m2m_request_queue -> v4l2_m2m_request_queue
To be consistent with the rest of the mem2mem helpers,
rename vb2_m2m_request_queue to v4l2_m2m_request_queue.

This is just a cosmetic change.

7cf7b2e977 media: vicodec: lower minimum height to 360
Lower the minimum height to 360 to be consistent with the webcam input of vivid.

The 480 was rather arbitrary but it made it harder to use vivid as a source for
encoding since the default resolution when you load vivid is 640x360.

Pull new experimental media request API from Mauro Carvalho Chehab:
 "A new media request API

  This API is needed to support device drivers that can dynamically
  change their parameters for each new frame. The latest versions of
  Google camera and codec HAL depends on such feature.

  At this stage, it supports only stateless codecs.

  It has been discussed for a long time (at least over the last 3-4
  years), and we finally reached to something that seem to work.

  This series contain both the API and core changes required to support
  it and a new m2m decoder driver (cedrus).

  As the current API is still experimental, the only real driver using
  it (cedrus) was added at staging[1]. We intend to keep it there for a
  while, in order to test the API. Only when we're sure that this API
  works for other cases (like encoders), we'll move this driver out of
  staging and set the API into a stone.

  [1] We added support for the vivid virtual driver (used only for
  testing) to it too, as it makes easier to test the API for the ones
  that don't have the cedrus hardware"
