c9f49607f1 [media] v4l: vsp1: Disable VYUY on Gen3
The VYUY format isn't supported on Gen3 hardware, disable it.

Gen2 hardware supports VYUY in practice even though the documentation

fc6e514a72 [media] v4l: vsp1: Support multiple partitions per frame
Adapt vsp1_video_pipeline_run() such that it can iterate each partition
required for constructing this frame's display list chain in the event
that multiple display lists are required to process in hardware.

The first display list is held as the head list object, whilst any
following parition display lists are linked to the head by means of
vsp1_dl_list_add_chain().

Linking the chained display list headers to process using the auto start
mechanism of the hardware is performed during the vsp1_dl_list_commit().

df32c92451 [media] v4l: vsp1: Determine partition requirements for scaled images
The partition algorithm needs to determine the capabilities of each
entity in the pipeline to identify the correct maximum partition width.

Extend the vsp1 entity operations to provide a max_width operation and
use this call to calculate the number of partitions that will be
processed by the algorithm.

Gen 2 hardware does not require multiple partitioning, and as such
will always return a single partition.

76e48896c0 [media] v4l: vsp1: Support chained display lists
When display lists are linked in a chain, they will be processed
automatically by the hardware, with each list linking to the next. Only
on the last display list will the frame end interrupt be fired to mark
the completion event.

Upon frame-end, the chain will be iterated to release each display list
back to the free list.

The chained lists use case (image partitioning) can require up to 64
lists per frame in the worst case scenario, bump up the number of
preallocated lists.

bfb4d5be9e [media] v4l: vsp1: Repair race between frame end and qbuf handler
The frame-end function releases and completes the buffers on the input
and output entities of the pipe before marking the pipe->state as
'STOPPED'. This introduces a race whereby with the pipe->state still
'RUNNING', a QBUF handler can commence processing a frame before the
frame_end function has completed.

In the event that this happens, a frame queued by QBUF hangs due to the
incorrect pipe->state setting which prevents vsp1_pipeline_run from
issuing a CMD_STRCMD.

By locking the entire function we prevent this from occurring, but we
also change the locking state of the buffer release code. This has been
analysed visually as acceptable, but it must be considered that this now
causes the video->irqlock to be taken under the pipe->irqlock context.

e4e70a147a [media] v4l: vsp1: Prevent pipelines from running when not streaming
Pipelines can only be run if all their video nodes are streaming. Commit
b4dfb9b35a ("[media] v4l: vsp1: Stop the pipeline upon the first
STREAMOFF") fixed the pipeline stop sequence, but introduced a race
condition that makes it possible to run a pipeline after stopping the
stream on a video node by queuing a buffer on the other side of the
pipeline.

Fix this by clearing the buffers ready flag when stopping the stream,
which will prevent the QBUF handler from running the pipeline.

283e4a8299 [media] media: platform: pxa_camera: make a standalone v4l2 device
This patch removes the soc_camera API dependency from pxa_camera.
In the current status :
 - all previously captures are working the same on pxa270
 - the s_crop() call was removed, judged not working
   (see what happens soc_camera_s_crop() when get_crop() == NULL)
 - if the pixel clock is provided by then sensor, ie. not MCLK, the dual
   stage change is not handled yet.
   => there is no in-tree user of this, so I'll let it that way

 - the MCLK is not yet finished, it's as in the legacy way,
   ie. activated at video device opening and closed at video device
   closing.
   In a subsequence patch pxa_camera_mclk_ops should be used, and
   platform data MCLK ignored. It will be the sensor's duty to request
   the clock and enable it, which will end in pxa_camera_mclk_ops.

e009ebd57b [media] media: platform: pxa_camera: convert to vb2
Convert pxa_camera from videobuf to videobuf2.

As the soc_camera was already compatible with videobuf2, the port is
quite straightforward.

The special case of this code in which the vb2 to prepare is "too
big" in terms of size for the new capture format, the pxa_camera will
fail.

This patch adds the H.264 video encoding capability in the V4L2 HVA
video encoder driver for STMicroelectronics SoC (hva-h264.c).

The main supported features are:
- profile: baseline, main, high, stereo high
- level: up to 4.2
- bitrate mode: CBR, VBR
- entropy mode: CABAC, CAVLC
- video aspect: 1x1 only

57b2c0628b [media] st-hva: multi-format video encoder V4L2 driver
This patch adds V4L2 HVA (Hardware Video Accelerator) video encoder
driver for STMicroelectronics SoC. It uses the V4L2 mem2mem framework.

This patch only contains the core parts of the driver:
- the V4L2 interface with the userland (hva-v4l2.c)
- the hardware services (hva-hw.c)
- the memory management utilities (hva-mem.c)

This patch doesn't include the support of specific codec (e.g. H.264)
video encoding: this support is part of subsequent patches.

ba75faf43d [media] rcar-fcp: Make sure rcar_fcp_enable() returns 0 on success
When resuming from suspend-to-RAM on r8a7795/salvator-x:

    dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
    PM: Device fe940000.fdp1 failed to resume noirq: error 1
    dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
    PM: Device fe944000.fdp1 failed to resume noirq: error 1
    dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
    PM: Device fe948000.fdp1 failed to resume noirq: error 1

According to its documentation, rcar_fcp_enable() returns 0 on success
or a negative error code if an error occurs.  Hence
fdp1_pm_runtime_resume() and vsp1_pm_runtime_resume() forward its return
value to their callers.

However, rcar_fcp_enable() forwards the return value of
pm_runtime_get_sync(), which can actually be 1 on success, leading to
the resume failure above.

To fix this, consider only negative values returned by
pm_runtime_get_sync() to be failures.
