Now that vidioc_s_ctrl is gone we want to remove that string from all
the codebase.
Besides, it isn't the correct name of this function anyway. It's clearly a
left-over from the past.

The driver has been converted to the control framework in the past:

This function is never called, the core will only use the control

The driver was missing support for query_ext_ctrl. Instead of adding a

let the ioctl framework emulate the old function.

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:

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

the vblank is written immediately when the control is set, as setting

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.

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

v4l2_query_ext_ctrl contains information that is missing in

With this change we can handle all the element_size information inside

Now that we are at it, remove the memset of the reserved fields, the
