Add support for the Raspberry Pi PiSP Back End.
The driver has been upported from the Raspberry Pi kernel at revision
f74893f8a0c2 ("drivers: media: pisp_be: Update seqeuence numbers of the
buffers").
The ISP documentation is available at:

This adds support for stateful V4L2 M2M based driver for Imagination E5010
JPEG Encoder [1] which supports baseline encoding with two different
quantization tables and compression ratio as demanded.
Support for both contiguous and non-contiguous YUV420 and YUV422 semiplanar
formats is added along with alignment restrictions as required by the
hardware.
System and runtime PM hooks are added in the driver along with v4l2 crop
and selection API support.
Minimum resolution supported is 64x64 and
Maximum resolution supported is 8192x8192.
All v4l2-compliance tests are passing [2] :
v4l2-compliance -s -f -a -d /dev/video0 -e /dev/video1
Total for e5010 device /dev/video0: 79, Succeeded: 79, Failed: 0,
Warnings: 0
NOTE: video1 here is VIVID test pattern generator
Also tests [3] were run manually to verify below driver features:
- Runtime Power Management
- Multi-instance JPEG Encoding
- DMABUF import, export support
- NV12, NV21, NV16, NV61 video format support
- Compression quality S_CTRL
- Cropping support using S_SELECTION
Existing V4L2 M2M based JPEG drivers namely s5p-jpeg, imx-jpeg and rcar_jpu
were referred while making this.

Add a driver for the Unicam camera receiver block on BCM283x processors.
It is represented as two video device nodes: unicam-image and
unicam-embedded which are connected to an internal subdev (named
unicam-subdev) in order to manage streams routing.

Add driver for Video Capture/Differentiation Engine (VCD) and Encoding
Compression Engine (ECE) present on Nuvoton NPCM SoCs. As described in
the datasheet NPCM750D_DS_Rev_1.0, the VCD can capture frames from
digital video input and compare two frames in memory, and then the ECE
can compress the frame data into HEXTILE format. This driver implements
V4L2 interfaces and provides user controls to support KVM feature, also
tested with VNC Viewer ver.6.22.826 and openbmc/obmc-ikvm.

The Atmel ISC will be moved to staging thus the atmel platform will only
have the ISI driver.
The new media-controller converted ISC driver will be placed inside a
dedicated microchip platform directory.
It is then natural to have the microchip-csi2dc moved to this new platform
directory.
The next step is to add the Microchip ISC driver to the new platform
directory and reside together with the Microchip CSI2DC driver.

The Hantro mainline driver has been used in production

out of staging, graduate the driver as well.

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.
On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

Just like media bus drivers, place platform drivers on a
submenu, in order to better organize user-selection:
Media drivers --->
*** media drivers ***
[*] Media USB Adapters --->
[*] Media PCI Adapters --->
-*- Radio Adapters --->
[*] Media platform devices --->
*** MMC/SDIO DVB adapters ***
< > Siano SMS1xxx based MDTV via SDIO interface
[*] V4L test drivers --->
[*] DVB test drivers --->
*** FireWire (IEEE 1394) Adapters ***
<*> FireDTV and FloppyDTV
*** common driver options ***
[ ] Enable Remote Controller support for Siano devices
[ ] Enable debugfs for smsdvb
As this submenu depends on MEDIA_PLATFORM_DRIVERS and defaults to "y",
there's no need to change already-existing .config entries, nor touch
the several make *_defconfig.
