4fbeef21f5 Revert "media: cx231xx: add USB ID 2040:8360 for Hauppauge WinTV-HVR-935"
This reverts commit bb2a391254.

The USB ID 2040:8360 was reported as a new revision
of Hauppauge HVR-935 and requested to be added to
the cx231xx driver. The issue is current generation
of Hauppauge 9x5 devices including 935, 955, and 975
have moved to em2828x usb bridge. Support for the
em2828x usb bridge and USB ID's for the new devices
has been submitted.

ec40b431f0 media: synopsys: csi2rx: add i.MX93 support
The i.MX93 uses a newer version of the DW CSI-2 controller with a changed
register layout and an integrated Image Pixel Interface (IPI), which
converts the received CSI-2 packets from byte to pixel format and produces
a pixel data bus containing vertical and horizontal synchronization
information.

The reset flow also differs, so add the .assert_reset(), .deassert_reset(),
and .idi_enable() callbacks to support it.

bac5990b88 media: i2c: imx283: add support for non-continuous MIPI clock mode
Add support for selecting between continuous and non-continuous MIPI clock
mode.

Previously, the CSI-2 non-continuous clock endpoint flag was ignored and
the sensor was always configured for non-continuous clock mode. For
existing device tree nodes that do not have this property enabled, this
update will therefore change the actual clock mode.

5d150fa0f1 media: i2c: ov08d10: fix image vertical start setting
The current settings for the "image vertical start" register appear to be
incorrect. While this only results in an incorrect start line for native
modes, this faulty setting causes actual problems in binning mode. At least
on an i.MX8MP test system, only corrupted frames could be received.
To correct this, the recommended settings from the reference register sets
are used for all modes. Since this shifts the start by one line, the Bayer
pattern also changes, which has also been corrected.

7c39f48568 media: uvcvideo: Fix bug in error path of uvc_alloc_urb_buffers
Recent cleanup introduced a bug in the error path of
uvc_alloc_urb_buffers(). If there is not enough memory for the
allocation the following error will be triggered:

[  739.196672] UBSAN: shift-out-of-bounds in mm/page_alloc.c:1403:22
[  739.196710] shift exponent 52 is too large for 32-bit type 'int'

Resulting in:
[  740.464422] BUG: unable to handle page fault for address: fffffac1c0800000

The reason for the bug is that usb_free_noncoherent is called with an
invalid size (0) instead of the actual size of the urb.

This patch takes care of that.

fd55319692 media: Add t4ka3 camera sensor driver
Add the t4ka3 driver from:
https://github.com/kitakar5525/surface3-atomisp-cameras.git

With many cleanups / changes (almost a full rewrite) to make it suitable
for upstream:

* Remove the VCM and VCM-OTP support, the mainline kernel models VCMs and
  calibration data eeproms as separate v4l2-subdev-s.

* Remove the integration-factor t4ka3_get_intg_factor() support and IOCTL,
  this provided info to userspace through an atomisp private IOCTL.

* Turn atomisp specific exposure/gain IOCTL into standard v4l2 controls.

* Use normal ACPI power-management in combination with runtime-pm support
  instead of atomisp specific GMIN power-management code.

* Turn into a standard V4L2 sensor driver using
  v4l2_async_register_subdev_sensor().

* Add vblank, hblank, and link-freq controls; drop get_frame_interval().

* Use CCI register helpers.

* Calculate values for modes instead of using fixed register-value lists,
  allowing arbritrary modes.

* Add get_selection() and set_selection() support

* Add a CSI2 bus configuration check

This was tested on a Xiaomi Mipad2 tablet which has a T4KA3 sensor with
DW9761 VCM as back sensor.

The empia em2828X usb bridge contains previous functionality,
but also contains an embedded video decoder. The implemented
capabilities include composite and s-video inputs, as well as
analog TV. Analog TV is expected in CVBS format, it must be
demodulated already.

Media controller decoder entity is included so pipeline
verification passes and graph is properly constructed.

Analog TV bits based off cx231xx driver.

d17d21bb0e media: renesas: vsp1: histo: Fix format setting
The histogram .set_fmt() handler suffers from two problems:

- When operating on the source pad, it returns correct information to
  userspace, but does not store the format in the subdev state.
  Subsequent calls to .get_fmt(), handled by the
  vsp1_subdev_get_pad_format() helper, will not return the correct
  information.

- When operating on the sink pad, it uses the
  vsp1_subdev_set_pad_format(), which propagates the sink format to the
  source, incorrectly overwriting the fixed source format.

The first issue could be fixed by implementing the set format operation
with vsp1_subdev_get_pad_format() on the source pad, if it wasn't that
.set_fmt() is also used to initialize the subdev state in
vsp1_entity_init_state(). The histogram would need a custom
.init_state() handler.

As the second issue would anyway overwrite the format, and therefore
requires a custom .set_fmt() implementation, fix both issues without
using the helpers.

55823379e6 media: renesas: vsp1: rpf: Fix crop left and top clamping
The RPF doesn't enforces the alignment constraint on the sink pad
format, which could have an odd size, possibly down to 1x1. In that
case, the upper bounds for the left and top coordinates clamping would
become negative, cast to a very large positive value. Incorrect crop
rectangle coordinates would then be incorrectly accepted.

A second issue can occur when the requested left and top coordinates are
negative. They are cast to a large unsigned value, clamped to the
maximum. While the calculation will produce valid values for the
hardware, this is not compliant with the V4L2 specification that
requires values to be adjusted to the closest valid value.

Fix both issues by switching to signed clamping, with an explicit
minimum to adjust negative values, and adjusting the clamp bounds to
avoid negative upper bounds.

46d3ad6070 media: renesas: vsp1: Fix code checks in frame size enumeration
The media bus code passed to the .enum_frame_size() operation for the
sink pad is required to be supported by the device, but not to match the
current format. All entities that use the vsp1_subdev_enum_frame_size()
helper, as well as the SRU and UDS entities that implement the operation
manually, perform the check incorrectly.

Fix the issue by implementing the correct code check in the
vsp1_subdev_enum_frame_size(). For the SRU and UDS, to avoid duplicating
code, use the vsp1_subdev_enum_frame_size() as a base and override the
enumerated size on the source pad with entity-specific constraints.

While at it, include the missing <linux/mutex.h> as the code locks
mutexes.

2c8fe1f142 media: uvcvideo: Add support for P010 pixel format
Add support for the P010 (10-bit Y/UV 4:2:0) pixel format to the
uvcvideo driver. This format is exposed by USB capture devices such as
the Magewell USB Capture HDMI 4K Pro when capturing HDR10 content.

P010 stores 10-bit Y and interleaved UV samples in 16-bit little-endian
words, with data in the upper 10 bits and zeros in the lower 6 bits.
This requires 2 bytes per sample, so bytesperline is wWidth * 2.

V4L2_PIX_FMT_P010 was added to the V4L2 core in commit 5374d8fb75
("media: Add P010 video format").

Based on the community DKMS patch from awawa-dev/P010_for_V4L2.
