Laurent Pinchart bffba4737b [media] v4l: vsp1: Fix tri-planar format support through DRM API
The vsp1 driver supports tri-planar formats, but the DRM API only passes
two memory addresses. Add a third one.

The FCP must be powered up for the FDP1 to function, even when the FDP1

Laurent Pinchart fd44aa9a25 [media] v4l: rcar-fcp: Don't force users to check for disabled FCP support
The rcar_fcp_enable() function immediately returns successfully when the
FCP device pointer is NULL to avoid forcing the users to check the FCP
device manually before every call. However, the stub version of the
function used when the FCP driver is disabled returns -ENOSYS
unconditionally, resulting in a different API contract for the two
versions of the function.

As a user that requires FCP support will fail at probe time when calling
rcar_fcp_get() if the FCP driver is disabled, the stub version of the
rcar_fcp_enable() function will only be called with a NULL FCP device.
We can thus return 0 unconditionally to align the behaviour with the
normal version of the function.

Sakari Ailus e42c475418 [media] doc-rst: 16-bit BGGR is always 16 bits
The V4L2_PIX_FMT_SBGGR16 format is documented to contain samples of fewer
than 16 bits. However, we do have specific definitions for smaller sample
sizes. Therefore, this note is redundant from the API point of view.

Currently only two drivers, am437x and davinci, use the
V4L2_PIX_FMT_SBGGR16 pixelformat currently. The sampling precision is
understood to be 16 bits in all current cases.

Remove the note on sampling precision.

Robert Jarzmik fcdf9bbc91 [media] media: platform: pxa_camera: change stop_streaming semantics
Instead of the legacy behavior where it was required to wait for all
video buffers to be finished by the hardware, use a cancel like strategy
: as soon as the stop_streaming() call is done, abort all DMA transfers,
report the already buffers as failed and return.

This makes stop_streaming() more a "cancel capture" than a "wait for end
of capture" semantic.

Robert Jarzmik 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.

Mauro Carvalho Chehab 9f8d3a2ee7 [media] v4l2-mem2mem.h: make kernel-doc parse v4l2-mem2mem.h again
The kernel-doc C parser doesn't like opaque structures. So,
document it on another way.

This should get rid of this warning:
	./include/media/v4l2-mem2mem.h:62: error: Cannot parse struct or union!
