2d29bcc8c2 media: tvp5150: fix switch exit in set control handler
The function only consists of a single switch case block without a
default case. Unsupported control requests are indicated by the -EINVAL
return code trough the last return statement at the end of the function. So
exiting just the switch case block returns the -EINVAL error code but the
hue control is supported and a zero should be returned instead.

Replace the break by a 'return 0' to fix this behaviour.

bd24db0410 media: tvp5150: fix width alignment during set_selection()
The driver ignored the width alignment which exists due to the UYVY
colorspace format. Fix the width alignment and make use of the the
provided v4l2 helper function to set the width, height and all
alignments in one.

c1a37dd5e8 media: v4l2: taint pads with the signal types for consumer devices
Consumer devices are provided with a wide different range of types
supported by the same driver, allowing different configutations.

In order to make easier to setup media controller links, "taint"
pads with the signal type it carries.

While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries
is actually the same as the normal video output.

The difference happens at the video/VBI interface:
	- for VBI, only the hidden lines are streamed;
	- for video, the stream is usually cropped to hide the
	  vbi lines.

5c4c4505b7 media: tvp5150: avoid going past array on v4l2_querymenu()
The parameters of v4l2_ctrl_new_std_menu_items() are tricky: instead of
the number of possible values, it requires the number of the maximum

otherwise it will go past the array bounds, as warned by KASAN:

4d471563d8 media: i2c: Fix pm_runtime_get_if_in_use() usage in sensor drivers
pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This
should not be considered an error. Generally the driver has enabled
runtime PM already so getting this error due to runtime PM being disabled
will not happen.

Instead of checking for lesser or equal to zero, check for zero only.
Address this for drivers where this pattern exists.

This patch has been produced using the following command:

$ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \

39dd23dc9d media: imx274: add cropping support via SELECTION API
Currently this driver does not support cropping. The supported modes
are the following, all capturing the entire area:

 - 3840x2160, 1:1 binning (native sensor resolution)
 - 1920x1080, 2:1 binning
 - 1280x720,  3:1 binning

The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the
one that matches the requested format.

Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target
V4L2_SEL_TGT_CROP to choose the captured area, with
V4L2_SEL_TGT_COMPOSE to choose the output resolution.

To maintain backward compatibility we also allow setting the compose
format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and
output format are computed in the common helper function
__imx274_change_compose(), which sets both to the same width/height
values.

Cropping also calls __imx274_change_compose() whenever cropping rect
size changes in order to reset the compose rect (and output format
size) for 1:1 binning.

Also rename enum imx274_mode to imx274_binning (and its values from
IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two
naming are equivalent. With cropping, the resolution could be
different, e.g. using 2:1 binning mode to crop 1200x960 and output a
600x480 format. Using binning in the names avoids any
misunderstanding. For the same reason, replace the 'size' field in
struct imx274_frmfmt with 'bin_ratio'.

279b4b9aaa media: imx274: use regmap_bulk_write to write multybyte registers
Currently 2-bytes and 3-bytes registers are set by very similar
functions doing the needed shift & mask manipulation, followed by very
similar for loops setting one byte at a time over I2C.

Replace all of this code by a unique helper function that calls
regmap_bulk_write(), which has two advantages:
 - sets all the bytes in a unique I2C transaction
 - removes lots of now unused code.

3ee47cad3e media: ov2680: Add Omnivision OV2680 sensor driver
This patch adds V4L2 sub-device driver for OV2680 image sensor.
The OV2680 is a 1/5" CMOS color sensor from Omnivision.
Supports output format: 10-bit Raw RGB.
The OV2680 has a single lane MIPI interface.

The driver exposes following V4L2 controls:
- auto/manual exposure,
- exposure,
- auto/manual gain,
- gain,
- horizontal/vertical flip,
- test pattern menu.
Supported resolution are only: QUXGA, 720P, UXGA.

The ADV7180 and ADV7182 transmit whole fields, bottom field followed
by top (or vice-versa, depending on detected video standard). So
for chips that do not have support for explicitly setting the field
mode via I2P, set the field mode to V4L2_FIELD_ALTERNATE.

I2P converts fields into frames using an edge adaptive algorithm. The
frame rate is the same as the 'field rate': e.g. X fields per second
are now X frames per second.

d272bc92c4 media: rename MEDIA_ENT_F_DTV_DECODER to MEDIA_ENT_F_DV_DECODER
The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.

Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.

We keep an alias to avoid breaking userspace applications.

Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.
These drivers are adv7604, adv7842 and tda1997x.
