The pad-aware version of v4l2_get_link_freq() tries to retrieve the link
frequency from the media bus configuration using the get_mbus_config
operation, and only if the subdevice does not implement this operation
falls back to the old method of getting it using the V4L2_CID_LINK_FREQ
or V4L2_CID_PIXEL_RATE control.
Update the VIN driver to use the pad-aware version to be able to support
subdevices that only provides the link frequency in the media bus
configuration. As the implementation falls back to the old method if the
subdevice doesn't support get_mbus_config, or doesn't provide a link
frequency in the v4l2_mbus_config struct, this is fully backward
compatible.

Rather than open-code a calculation of the format's bytesperline
and sizeimage, use the v4l2_fill_pixfmt() helper. This makes it
easier to support the CRU packed pixel formats without over
complicating the driver.
This change makes the .bpp member of struct rzg2l_cru_ip_format
superfluous - remove them.

Depending on if the capture session deals with fields or whole frames
interrupts can be generated at an end of field, or end of frame event.
The interrupt mask is setup to generate an interrupt on one of the two
events depending on what is needed when the VIN is started. The end of
field bit is set in both cases so controlling the mask that generates an
interrupt have been enough to control the two use-cases.
Before extending the interrupt handler to deal with other types of
interrupt events it is needs to extended to "capture complete" check for
correct the use-case in operation. Without this the simplification in
the handler can result in corrupted frames when the mask on what type of
events can generate an interrupt generated can no longer be assumed to
only be an "capture complete" event.
Which bit is checked matches which bit is enabled at configuration time
as which event can generate an interrupt for "capture complete". There
is no functional change.
While at it switch to use the BIT() macro to describe the bit positions
for the interrupt functions.

Complete the conversion from soc_camera to a full fledge media
controller enabled devices for all supported generations of the device.
All work is already done as this is already supported on Gen3, and
later.
All that is missing is removing all special cases for the non
media-graph call paths and use the common ones in their place.
The one change that stands out is dropping the doubling of the height in
the Gen2 scaler setup, rvin_scaler_gen2(). In the Gen2 non-MC world the
VIN size was set to match the video source subdevices, and if that was a
TOP/BOTTOM video source it needed to be doubled for the scaler to
function properly. In the MC world this is now handled by user-space
configuration of the pipeline and the adjustment is not needed.
Mark the completion of converting from soc_camera by injecting an

The VIN usage of v4l-async is complex and stems from organic growth of
the driver of supporting both private local subdevices (Gen2, Gen3) and
subdevices shared between all VIN instances (Gen3 and Gen4).
The driver used a separate notifier for each VIN for the private local
ones, and a shared group notifier for the shared ones. This was complex
and lead to subtle bugs when unbinding and later rebinding subdevices in
one of the notifiers having to handle different edge cases depending on
if it also had subdevices in the other notifiers etc.
To simplify this have the Gen2 devices allocate and form a VIN group
too. This way all subdevices on all models can be collect in a
single group notifier. Then there is only a single complete callback for
all where the video devices and subdevice nodes can be registered etc.

The link setup callback once acted on each VIN instance, and expected to
be called once for each VIN instance. This have changed as the driver
grew support for later hardware generations and the callback is now
expected to setup links for all VIN in the group.
The argument to the callback has however remained a pointer to a single
VIN instance. This pointer was then used to get the group structure. Fix
this and pass the group as the single argument to the link setup
callback making the expectation of the function clear.

When extending the driver with Gen4 support the iteration of over
possible remote subdevices changed from being R-Car CSI-2 Rx only to
also cover R-Car CSISP instances. In two loops updating the bounds
variable was missed.
This had no ill effect as the count the two values have always been the
same in the past. Fix it by looking at the array size.

Add D-PHY support for V4H in addition to the already supported C-PHY.
The common start-up procedure for C-PHY and D-PHY is shared, only PHY
setup differ. Extend the V4H setup with D-PHY support as documented in
the datasheet (Rev.1.21).
Most of the start-up procedure is only documented as magic values in
tables, there is little documentation to make the settings more clear.
Wherever possible formulas or lookup tables are used as they are
documented in the datasheet.

Prepare for adding D-PHY support to the driver by first updating the
generic startup procedure that covers both C-PHY and D-PHY operations.
The starting procedure where updated in later versions of the datasheet.
Most of the configuration is only documented as tables of magic values
in the documentation. Each step is however marked with a T<n> marker,
inject these markers in the comments to make it easier to map driver to
documentation.

Each AFE lane has a set of control and offset registers. The registers
themself are undocumented but later datasheets program more of them with
magic values. Before exploding the driver with more defines to name them
all rework the AFE ones to be able to address all controls and offsets.
Also move a stray define that is out of sequence.
There is no functional change.

The helper function to deal with calculating the link speed is designed
in such a way that it returns the correct type bps (bits per second) for
D-PHY and sps (symbols per second) for C-PHY. And for historical reasons
the function kept the name mbps.
This is confusing, fix it by having the function only deal with bps
values as this is the most common use-case and convert bps to sps in the
only function where it is needed to configure the C-PHY.

The vsp1 driver implements very partial colour space support: it
hardcodes the colorspace field on all video devices and subdevices to
V4L2_COLORSPACE_SRGB, regardless of the configured format. The
xfer_func, ycbcr_enc and quantization fields are not set (except for
hsv_enc for HSV formats on video devices). This doesn't match the
hardware configuration, which handles YUV data as encoding in BT.601
with limited range.
As a first step towards colour space configuration, keep the colour
space fields hardcoded, but set them based on the selected format type
(RGB, YUV or HSV).
While at it, remove an extra blank line.

The vsp1_dl library allows to program a display list and feed it
continuously to the VSP2. As an alternative operation mode, the library
allows to program the VSP2 in 'single shot' mode, where a display list
is submitted to the VSP on request only.
Currently the 'single shot' mode is only available when the VSP2 is
controlled by userspace, while it works in continuous mode when driven
by DRM, as frames have to be submitted to the display continuously.
For the VSPX use case, where there is no uapi support, we should however
work in single-shot mode as the ISP driver programs the VSPX on
request.
Initialize the display lists in single shot mode in case the VSP1 is
controlled by userspace or in case the pipeline features an IIF entity,
as in the VSPX case.
