Add V4L2_CID_DIGITAL_GAIN to control explicitly digital gain.
We already have analogue gain control which the digital gain control
complements. Typically higher quality images are obtained using analogue
gain only as the digital gain does not add information to the image
(rather it may remove it).Signed-off-by: Sakari Ailus

Calling S_STREAM OFF multiple times on a video device is valid, although

lower than zero, just ignore the subsequent S_STREAM calls and correct

This patch adds a call to imx_media_fill_default_mbus_fields() in the
*_try_fmt() functions at the sink pads, to set empty field order and
colorimetry parameters.If the field order is set to ANY, choose the currently set field order
at the sink pad. If the colorspace is set to DEFAULT, choose the
current colorspace at the sink pad. If any of xfer_func, ycbcr_enc
or quantization are set to DEFAULT, either choose the current sink pad
setting, or the default setting for the new colorspace, if non-DEFAULT
colorspace was given.If a format is destined to be routed through the Image Converter,
fixed quantization and Y`CbCr encoding must be set.Colorimetry is also propagated from sink to source pads anywhere
this has not already been done.Signed-off-by: Steve Longerbeam

Add frame size and frame interval enumeration to CSI.
CSI can downscale the image independently horizontally and vertically by a
factor of two, which enumerates to four different frame sizes at the
output pads. The input pad supports a range of frame sizes.CSI can also drop frames, resulting in frame rate reduction, so
enumerate the resulting possible output frame rates.Signed-off-by: Russell King

Adds MIPI CSI-2 Receiver subdev driver. This subdev is required
for sensors with a MIPI CSI2 interface.- Switch from the v4l2_of_ APIs to the v4l2_fwnode_ APIs.
- Add the function csi2ipu_gasket_init() to initialize the gasket at
s_power(ON). The gasket needs to be programmed with the correct color
component ordering to handle UYVY vs. YUYV ordered mbus formats from
sensors. Note that the description of the CSI2IPU_GASKET register in
the i.MX6 reference manual is wrong w.r.t bit 2 (the manual refers to
this register as CSI2_SW_RST): setting bit 2 selects YUYV order, not UYVY.Signed-off-by: Steve Longerbeam

This is a set of three media entity subdevice drivers for the i.MX
Image Converter:- Pre-process Router: Takes input frames from CSI0, CSI1, or VDIC.
Two output pads enable either or both of the preprocess tasks
below. If the input is from one of the CSIs, both proprocess task
links can be enabled to process frames from that CSI simultaneously.
If the input is the VDIC, only the Pre-processing Viewfinder task
link can be enabled.- Pre-processing Encode task: video frames are routed directly from
the CSI and can be scaled, color-space converted, and rotated.
Scaled output is limited to 1024x1024 resolution. Output frames
are routed to the prpenc capture device.- Pre-processing Viewfinder task: this task can perform the same
conversions as the pre-process encode task, but in addition can
be used for hardware motion compensated deinterlacing. Frames can
come either directly from the CSI or from the VDIC. Scaled output
is limited to 1024x1024 resolution. Output frames are routed to
the prpvf capture device.Signed-off-by: Steve Longerbeam

This driver can handle SoC internal and external video bus multiplexers,
controlled by mux controllers provided by the mux controller framework,
such as MMIO register bitfields or GPIOs. The subdevice passes through
the mbus configuration of the active input to the output side.Since the mux framework is not yet merged, this driver contains
temporary mmio-mux support to work without the framework. The driver
should be converted to use the multiplexer API once the "mux: minimal
mux subsystem" and "mux: mmio-based syscon mux controller" patches are
merged.Signed-off-by: Sascha Hauer

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.Signed-off-by: Ramesh Shanmugasundaram
