Most of the times that we have to call uvc_status_(get|put) we need to
call the usb_autopm_ functions.
Create a new pair of functions that automate this for us. This
simplifies the current code and future PM changes in the driver.

Add a variable in the file handle state to figure out if a camera is in
the streaming state or not. This variable will be used in the future for
power management policies.
Now that we are at it, make use of guards to simplify the code.

Once device_register() failed, we should call put_device() to
decrement reference count for cleanup. Or it could cause memory leak.
And move callback function v4l2_device_release() and v4l2_device_get()
before put_device().
As comment of device_register() says, 'NOTE: _Never_ directly free
@dev after calling this function, even if it returned an error! Always
use put_device() to give up the reference initialized in this function
instead.'

In commit cfa49ff0558a ("media: i2c: imx335: Support 2592x1940 10-bit
mode") the IMX335 driver was extended to support multiple output
bitdepth modes.
This incorrectly extended the frame size enumeration to check against
the supported mbus_codes array instead of the supported mode/frame
array. This has the unwanted side effect of reporting the currently
supported frame size 2592x1944 three times.
Fix the check accordingly to report a frame size for each supported
size, which is presently only a single entry.

v4l2_find_nearest_size() returns a mode from sensor driver's mode list
that is a best match width and height wise for the sensor. Some drivers
have different set of available modes depending on the number of lanes.
While this could be handled within a driver by providing different lists
of modes, provide a helper v4l2_find_nearest_size_conditional() to ignore
modes that aren't available.
Also use size_t for the array index and remove extra commas while at it.

Pixel per line (PPL) is calculated as pixel_rate / (VTS * FPS), which
is not decided by MIPI CSI-2 link frequency. PPL can vary while link
frequency keeps the same. If PPL is wrong, the h_blank = PPL - width
is also wrong then FPS control is inaccurate.

1. Move PPL from link_freq_config to ov13b10_mode
2. Add PPL value for different modes
3. Use PPL from mode to calculate h_blank

Lt6911uxe is used in IPU6 / x86 platform, worked with an out-of-tree
int3472 patch and upstream intel/ipu6 before. It is only used on ACPI
platforms till now and there are no devicetree bindings for this
driver.
The upstream int3472 driver uses "hpd" instead of "readystat" now.
this patch updates the irq_gpio name to "hpd" accordingly, so that
mere users can now use the upstream version directly without relying
on out-of-tree int3472 pin support.
The new name "hpd" (Hotplug Detect) aligns with common naming
conventions used in other drivers(like adv7604) and documentation.

- Auto exposure from the sensor, or manual exposure mode
- HDR subtraction mode, allowing edge detection and background removal
- Auto exposure cold start, using configuration values from last stream
to start the next one
- LED GPIOs for illumination
- Most standard camera sensor features (hblank, vblank, test patterns,

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 RWPF source pad media bus code can only be different from the sink
pad code when enabling color space conversion, which can only convert
between RGB and YUV. If the sink pad code is HSV, no conversion is
possible. Fix the pad set format handler to reflect this hardware
limitation.
