Add driver for Renesas Capture Engine Unit (CEU).
The CEU interface supports capturing 'data' (YUV422) and 'images'
(NV[12|21|16|61]).
This driver aims to replace the soc_camera-based sh_mobile_ceu one.
Tested with ov7670 camera sensor, providing YUYV_2X8 data on Renesas RZ
platform GR-Peach.
Tested with ov7725 camera sensor on SH4 platform Migo-R.

This driver adds support for the Tegra CEC IP. It is based on the
NVIDIA drivers/misc/tegra-cec driver in their 3.10 kernel.
This has been converted to the CEC framework and cleaned up.
Tested with my Jetson TK1 board. It has also been tested with the
Tegra X1 in an embedded product.
Note of warning for the Tegra X2: this SoC supports two HDMI outputs,
but only one CEC adapter and the CEC bus is shared between the
two outputs. This is a design mistake and the CEC adapter can
control only one HDMI output. Never hook up both HDMI outputs
to the CEC bus in a hardware design: this is illegal as per the
CEC specification.
The CEC bus can be shared between multiple inputs and zero or one
outputs, but not between multiple outputs.

Rockchip RGA is a separate 2D raster graphic acceleration unit. It
accelerates 2D graphics operations, such as point/line drawing, image
scaling, rotation, BitBLT, alpha blending and image blur/sharpness
The driver supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- rotation
- flip
- alpha blending
The code in rga-hw.c is used to configure regs according to operations
The code in rga-buf.c is used to create private mmu table for RGA.

Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework.
While I have heard of SoCs that use the GPIO pin for CEC (apparently an
early RockChip SoC used that), the main use-case of this driver is to
function as a debugging tool.
By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example
it turns it into a CEC debugger and protocol analyzer.
With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed.
But of course it can also be used with any hardware project where the
HDMI CEC line is hooked up to a pull-up gpio line.
In addition this has (optional) support for tracing HPD changes if the
HPD is connected to a GPIO.

This patch adds Digital Radio Interface (DRIF) support to R-Car Gen3 SoCs.
The driver exposes each instance of DRIF as a V4L2 SDR device. A DRIF
device represents a channel and each channel can have one or two
sub-channels respectively depending on the target board.
DRIF supports only Rx functionality. It receives samples from a RF
frontend tuner chip it is interfaced with. The combination of DRIF and the
tuner device, which is registered as a sub-device, determines the receive
sample rate and format.
In order to be compliant as a V4L2 SDR device, DRIF needs to bind with
the tuner device, which can be provided by a third party vendor. DRIF acts
as a slave device and the tuner device acts as a master transmitting the
samples. The driver allows asynchronous binding of a tuner device that
is registered as a v4l2 sub-device. The driver can learn about the tuner
it is interfaced with based on port endpoint properties of the device in
device tree. The V4L2 SDR device inherits the controls exposed by the
tuner device.
The device can also be configured to use either one or both of the data
pins at runtime based on the master (tuner) configuration.

The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.
Move those sources to media/cec as well.
The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.
Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).
Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.
CEC drivers should now depend on CEC_CORE.
CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.
The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

IPC (Inter Process Communication) support for communication with
DELTA coprocessor firmware using rpmsg kernel framework.
Based on 4 services open/set_stream/decode/close and their associated
rpmsg messages.
The messages structures are duplicated on both host and firmware
side and are packed (use only of 32 bits size fields in messages
structures to ensure packing).
Each service is synchronous; service returns only when firmware
acknowledges the associated command message.
Due to significant parameters size exchanged from host to copro,
parameters are not inserted in rpmsg messages. Instead, parameters are
stored in physical memory shared between host and coprocessor.
Memory is non-cacheable, so no special operation is required
to ensure memory coherency on host and on coprocessor side.
Multi-instance support and re-entrance are ensured using host_hdl and
copro_hdl in message header exchanged between both host and coprocessor.
This avoids to manage tables on both sides to get back the running context
of each instance.

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.

The s5p-tv driver has been replaced by the exynos drm driver for quite a

of which this one is considered dead code by Samsung.
