Several camera sensor drivers access the "clock-frequency" property
directly to retrieve the external clock rate, or modify the clock rate
of the external clock programmatically. Both behaviours are valid on
a subset of ACPI platforms, but are considered deprecated on OF
platforms, and do not support ACPI platforms that implement MIPI DisCo
for Imaging. Implementing them manually in drivers is deprecated, as
that can encourage cargo-cult and lead to differences in behaviour
between drivers. Instead, drivers should use the
devm_v4l2_sensor_clk_get() helper.
This driver supports ACPI platforms only. It retrieves the clock rate
from the "clock-frequency" property. If the rate does not match the
expected rate, the driver prints a warning. This is correct behaviour
for ACPI.
Switch to using the devm_v4l2_sensor_clk_get() helper. This does not
change the behaviour on ACPI platforms that specify a clock-frequency
property and don't provide a clock. On ACPI platforms that provide a
clock, the clock rate will be set to the value of the clock-frequency
property. This should not change the behaviour either as this driver
expects the clock to be set to that rate, and wouldn't operate correctly
otherwise.

The driver needs to access the struct device in many places, and
retrieves it from the i2c_client itself retrieved with
v4l2_get_subdevdata(). Store it as a pointer in struct ov08d10 and
access it from there instead, to simplify the driver.

This driver supports ACPI and OF platforms. The "clocks" property is
specified as mandatory in the DT bindings and the "clock-frequency"
property is not allowed. The driver retrieves the clock and its rate if
present, and falls back to retrieving the rate from the
"clock-frequency" property otherwise. If the rate does not match the
expected rate, the driver fails probing. This is correct behaviour for
ACPI, and for OF platforms that comply with the documented DT bindings.

property. This should not change the behaviour either as this driver
expects the clock to be set to that rate, and wouldn't operate correctly

The behaviour is also unchanged on OF platforms that comply with the DT

could easily be handled by switching to the
devm_v4l2_sensor_clk_get_legacy() helper designed to preserve
non-compliant behaviour.

The ov6650 driver was introduced in v2.6.37 to support the OMAP1-based
Amstrad Delta video phone. The platform still has a board file in the
kernel, but support for the camera was dropped in commit ce548396a433
("media: mach-omap1: board-ams-delta.c: remove soc_camera dependencies")
in v5.9. The driver has been unused since as it has received neither
ACPI nor DT support.
The ov6650 driver is one of the last sensor drivers calling
clk_set_rate(). This is deprecated, and calls to the function are being
removed to avoid cargo-cult. As the driver is unlikely to ever be used
again, drop it instead of trying to avoid call clk_set_rate().

The mediabus code is device dependent, but the probe() function
thought that device_get_match_data() would return the code directly,
when in fact it returned a pointer to a struct mt9p031_model_info.
As a result, the initial mbus code was garbage.
Tested with a BeagleBoard xM and a Leopard Imaging LI-5M03 sensor board.

Add a qcm2290 compatible binding to the Venus core.
The maximum concurrency is video decode at 1920x1080 (FullHD) with video
encode at 1280x720 (HD).
The driver is not available to firmware versions below 6.0.55 due to an
internal requirement for secure buffers.
The bandwidth tables incorporate a conservative safety margin to ensure
stability under peak DDR and interconnect load conditions.

The AR50_LITE is a simplified variant of the AR50 video core, designed for
power and cost-efficient platforms.
It supports hardware-accelerated decoding of H.264, HEVC, and VP9 formats,
and provides encoding support for H.264 and HEVC.
This commit prepares the framework to enable the AR50_LITE (it does not
enable it).

Add support for specifying the minimum firmware version required for
correct operation.
When set, the driver compares this value against the version reported by
the firmware: if the firmware is older than required, driver
initialization will fail.
The version check is performed before creating dynamic device tree
nodes, to avoid the need for reverting nodes on failure.

When starting venus with the "no_tz" code path, IRIS2 needs the same
boot/reset sequence as IRIS2_1. This is because most of the registers were
moved to the "wrapper_tz_base", which is already defined for both IRIS2 and
IRIS2_1 inside core.c. Add IRIS2 to the checks inside firmware.c as well to
make sure that it uses the correct reset sequence.
Both IRIS2 and IRIS2_1 are HFI v6 variants, so the correct sequence was
used before commit c38610f8981e ("media: venus: firmware: Sanitize
per-VPU-version").

Bios are embedded into other structures, and at least spare is unhappy
about embedding structures with variable sized arrays. There's no
real need to the array anyway, we can replace it with a helper pointing
to the memory just behind the bio, and with the previous cleanups there
is very few site doing anything special with it.
