Fix the mismatch between clock list and clock rate table for CSID lite
instances. The current implementation has 5 clocks defined but only 2
are actually needed (vfe_lite_csid and vfe_lite_cphy_rx), while the
clock rate table doesn't match this configuration.
Update both clock list and rate table to maintain consistency:
- Remove unused clocks: cpas_vfe_lite, vfe_lite_ahb, vfe_lite
- Update clock rate table to match the remaining two clocks

During concurrency testing, multiple instances can run in parallel, and
each instance uses its own inst->lock while the core->lock protects the
list of active instances. The race happens because these locks cover
different scopes, inst->lock protects only the internals of a single
instance, while the Macro Blocks Per Frame (MBPF) checker walks the
core list under core->lock and reads fields like fmt_src->width and
fmt_src->height. At the same time, iris_close() may free fmt_src and
fmt_dst under inst->lock while the instance is still present in the core
list. This allows a situation where the MBPF checker, still iterating
through the core list, reaches an instance whose fmt_src was already
freed by another thread and ends up dereferencing a dangling pointer,
resulting in a use-after-free. This happens because the MBPF checker
assumes that any instance in the core list is fully valid, but the
freeing of fmt_src and fmt_dst without removing the instance from the
core list is not correct.
The correct ordering is to defer freeing fmt_src and fmt_dst until after
the instance has been removed from the core list and all teardown under
the core lock has completed, ensuring that no dangling pointers are ever
exposed during MBPF checks.

Currently the driver switches the vcodec GDSC to hardware (HW) mode
before firmware load and boot sequence. GDSC can be powered off, keeping
in hw mode, thereby the vcodec registers programmed in TrustZone (TZ)
carry default (reset) values.
Move the transition to HW mode after firmware load and boot sequence.
The bug was exposed with driver configuring different stream ids to
different devices via iommu-map. With registers carrying reset values,
VPU would not generate desired stream-id, thereby leading to SMMU fault.
For vpu4, when GDSC is switched to HW mode, there is a need to perform
the reset operation. Without reset, there are occasional issues of
register corruption observed. Hence the vpu GDSC switch also involves
the reset.

The recent change in commit 1dabf00ee206 ("media: iris: gen1: Destroy
internal buffers after FW releases") introduced a regression where
session_release_buf() may free the buffer. The caller,
iris_release_internal_buffers(), continued to access `buffer` after the
call, leading to a potential use-after-free.
Fix this by setting BUF_ATTR_PENDING_RELEASE before calling
session_release_buf(), and reverting the flag if the call fails. This
ensures no dereference occurs after potential freeing.

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.

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.

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

Initialized and left to themselves some boards with analog inputs,
on some modern platforms can throw critical errors which prevents
even digital from working thereafter. If analog is never used this
module parameter allows analog to be disabled on a card by card
basis.
It is already possible to disable analog audio.
For example, to disable for Hauppauge QuadHD with analog functionality:
options cx23885 disable_analog_video=56,57
can be placed insode of /etc/modprobe.d/cx23885.conf

Hauppauge 416e products have moved to using the 3103C satellite
demod. This demod behaves mostly like a 3103b, but has
different initialization, clocking, and lock operations.
This Linux code was reverse egineered entirely
using a Windows reference driver.

The Hauppauge HVR-935, HVR-955, and HVR-975 have moved
from cx231xx bridge to em2828x bridge.
The following USB device id's are new:
2040:0360 - HVR-935 ISOC transport
2040:8360 - HVR-935 Bulk transport
2040:0366 - HVR-955 ISOC transport
2040:8366 - HVR-955 Bulk transport
2040:036a - HVR-975 ISOC transport
2040:836a - HVR-975 Bulk transport
The devices all now utilize si2177 tuner. Capabilities are:
- Digital TV
- Composite video input
- S-Video input
- Analog stereo input
HVR-935 has DVB-C/T/T2 demod (si2168).
HVR-955 has ATSC/QAM demod (lgdt3306a).
HVR-975 has both ATSC/QAM and DVB-C/T/T2 demods.

The si2177 is very closely related to si2157, with slight differences
when doing analog operations. Digital is left as is, but analog needs
to be configured specially because the signal is internally demodulated
and CVBS video is output directly from the tuner.
Verified locked and working with all supported standards.

Fix em28xx driver to accommodate a device with two i2c client demods.
The em28xx driver already had a multi frontend aware device struct,
with two fe, just not two i2c client demods. Since Hauppauge HVR975
has transitioned from cx231xx to em2828X, this is required for full
functionality of the devices.

When the driver was converted to VB2 the original function to fix
green frame detection was removed and a default vb2 dqbuf function
was used instead. This vb2 dqbuf function leads to green frames not
being detected and correupting stream captures.
The vidioc_dqbuf function checks the greenscreen flag, and, if set
resets the stream to discard the green frame and decode a real frame.

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.

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.

The histogram media bus code enumeration does not check the index when
operating on the source pad, resulting in an infinite loop if userspace
keeps enumerating code without any loop boundary. Fix it by returning an
error for indices larger than 0 as the pad supports a single format.

The HSIT entity performs format conversion, which leads to incorrect
results with the vsp1_subdev_enum_frame_size() helper. Implement a
