The Cadence CSI-2 RX Controller is an hardware block meant to be used as a
bridge between a CSI-2 bus and pixel grabbers.
It supports operating with internal or external D-PHY, with up to 4 lanes,
or without any D-PHY. The current code only supports the latter case.
It also support dynamic mapping of the CSI-2 virtual channels to the
associated pixel grabbers, but that isn't allowed at the moment either.

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.

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.

By using the CEC notifier framework there is no longer any reason
to manually set the physical address. This was the one blocking
issue that prevented this driver from going out of staging, so do
this move as well.

Currently, IMX_VDOA and VIDEO_CODA only builds on ARCH_MXC.
That prevented me to build-test the driver, causing a bad patch
to be applied, and to see other warnings on this driver.
Hans wrote a similar patch, but his version was fold with a
warning fixup hunk.
So, I opted to keep my version.

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 creates 4 static debugfs entries to dump:
- the device-related information ("st-hva/device")
- the list of registered encoders ("st-hva/encoders")
- the current values of the hva registers ("st-hva/regs")
- the information about the last closed instance ("st-hva/last")
It also creates dynamically a debugfs entry for each opened instance,
("st-hva/<instance identifier>") to dump:
- the information about the frame (format, resolution)
- the information about the stream (format, profile, level,
resolution)
- the control parameters (bitrate mode, framerate, GOP size...)
- the potential (system, encoding...) errors
- the performance information about the encoding (HW processing
duration, average bitrate, average framerate...)
Each time a running instance is closed, its context (including the
debug information) is saved to feed, on demand, the last closed
instance debugfs entry.

from a custom macroblock tiled format produced by the CODA960 decoder
into linear formats that can be used for scanout.

Commit 4710b752e0 ("[media] v4l: Add Renesas R-Car FDP1 Driver") in the
v4l-dvb tree adds CONFIG_VIDEO_RENESAS_FDP1.
It calls into the FCP driver, but when there is no dependency, FCP might
be a module while FDP1 is built-in.
We have the same logic in VIDEO_RENESAS_VSP1, which also depends on
FCP not being a module when it is built-in itself.

In preparation to add scaler support into VIP we need to
turn sc.c into its own kernel module.
Add support for multiple SC memory block as VIP contains
2 scaler instances.
This is done by passing the resource name to sc_create() and
modify the vpe invocation accordingly.

Port (VIP).
In preparation for this we need to turn vpdma into its own
