v4l2_queryctrl is a subset of v4l2_query_ext_ctrl. If the driver does
not implement v4l2_queryctrl we can implement it with
v4l2_query_ext_ctrl.

The video_device for the MPEG encoder did not set device_caps.
Add this, otherwise the video device can't be registered (you get a
WARN_ON instead).
Not seen before since currently 417 support is disabled, but I found
this while experimenting with it.

While the CEC adapter is configuring, it is not possible to transmit a
CEC message with the CEC_MSG_FL_RAW flag set as this is blocked at the
ioctl level. Check if this flag is set, and if so, allow the message to
be transmitted. This is useful for debugging if the display has no
physical address (typically because the HPD is pulled low while in
Standby).

This card has the following ICs: Hybrid tuner TDA18271, CX23888 PCIe
bridge/demodulator/decoder (and DVB-T demodulator AF9013S, which is
not within the scope of this patch). It has the following inputs: Tuner,
S-Video, Composite (shared with the luma input of S-Video) and Audio L/R
RCA. VID:PID is 1461:e139. When the patch is applied and the cx23885
kernel module is built and loaded, the following dmesg can be seen:

The card has to be defined in cx23885-cards.c (firmware also has to be

cx23885-video.c. Analog tuning, composite, s-video and stereo audio

We should put/leave the sensor in reset when requesting the GPIO, after
requesting it there are 2 possible scenarios and having the GPIO driven
low is no good in either scenario:
1. The sensor was in ACPI D0 before probe() runs, in this case
ov08x40_power_on() + ov08x40_identify_module() will run immediately
after requesting the GPIO and ov08x40_power_on() starts with driving
the GPIO high. So if the GPIO was already high it will very shortly
be driven low, more of a spike to low then actually properly be driven
low. Which may leave the sensor in a confused state.
If we request the GPIO to be high at request time then power_on() will
driver it high again (no-op) and then sleep for 1-2 ms, so no spike.
2. The sensor was in ACPI D3 / off before probe(), in this case probe()
leaves the sensor alone. But when the sensor is off its reset line
should be driven high not low.

When the vblank v4l2 control is set, it does not get written to the
hardware unless exposure is also changed. Change the behavior such that
the vblank is written immediately when the control is set, as setting
the vblank without changing the exposure is a valid use case (such as
for changing the frame rate).

The LLP_MIN of 3560 is only needed to fix artefacts seen with binned
resolutions. As increasing the LLP reduces the highest possible
framerate by ~3%, use the old default minimum of 3448 if we are not
doing 2x2 analog binning.
Also restore the fll_def value for non-binned modes in the modes
definition to restore the default mode framerate to 30fps.

The imx219_get_binning() function currently returns two separate pieces
of information, the return value is the binning mode enum, and the bin_h
and bin_v references are updated with whether to perform binning in
horizontal and vertical dimensions.
It is simpler to combine both of these pieces of information, and
directly update the bin_h and bin_v references with the register value
that we will write to the sensor, which includes if the binning is
digital or analog mode, thus allowing us to remove the superfluous
binning mode enum.
This is only a style change for the driver, with no functionality
updated.

The bus_info in v4l2_capability of IPU6 isys v4l2_dev is missing.
The driver didn't set the dev_parent of v4l2_dev, its parent is set
to its parent auxdev which is neither platform nor PCI device, thus
media_set_bus_info() will not set the bus_info of v4l2_capability, then
`v4l2-ctl --all` cannot show the bus_info.
This patch fixes it by setting the dev_parent of video_device and v4l2
framework can detect the device type and set the bus_info instead.

We want to support fetching the min and max values with g_ext_ctrls,
this patch is a preparation for that.
Instead of abusing uvc_query_v4l2_ctrl(), add an extra parameter to
uvc_ctrl_get, so it can support fetching the default value.

Be consistent with uvc_get_le_value() and do the menu translation there.
Note that in this case, the refactor does not provide much... but
consistency is a nice feature.

map->get() gets a value from an uvc_control in "UVC format" and converts
it to a value that can be consumed by v4l2.
Instead of using a special get function for V4L2_CTRL_TYPE_MENU, we
were converting from uvc_get_le_value in two different places.
Move the conversion to uvc_get_le_value().

sfr->buf_size is in shared memory and can be modified by malicious user.
OOB write is possible when the size is made higher than actual sfr data
buffer. Cap the size to allocated size for such cases.
