0a07e09085 I2C core removes an argument from the i2c_mux_add_adapter() call to
further deprecate class based I2C device instantiation. All users are
 converted, too. Other that that, Andi collected a number if I2C host
 driver patches. Those merges have their own description.

fec1982d70 i2c: mux: Remove class argument from i2c_mux_add_adapter()
99a741aa7a ("i2c: mux: gpio: remove support for class-based device
instantiation") removed the last call to i2c_mux_add_adapter() with a
non-null class argument. Therefore the class argument can be removed.

Note: Class-based device instantiation is a legacy mechanism which
shouldn't be used in new code, so we can rule out that this argument
may be needed again in the future.

6983352784 media: ov2740: Ensure proper reset sequence on probe()
Before this commit on probe() the driver would do:

reset=1                // from probe() calling gpiod_get(GPIOD_OUT_HIGH)
reset=0                // from resume()
msleep(20)             // from resume()

So if reset was 0 before getting the GPIO the reset line would only be
driven high for a very short time and sometimes there would be errors
reading the id register afterwards.

Add a msleep(20) after getting the reset line to ensure the sensor is
properly reset:

reset=1                // from probe() calling gpiod_get(GPIOD_OUT_HIGH)
msleep(20)             // from probe()
reset=0                // from resume()
msleep(20)             // from resume()

d89218e48d media: ov2680: Stop sending more data then requested
There is no reason to send OV2680_END_MARGIN extra columns on top of
the mode width and the same for sending extra lines over the mode height.

This sending of extra lines/columns was inherited from the atomisp
ov2680 driver, it is unclear why this was done and this complicates
adding V4L2_CID_VBLANK support, so remove it.

24034af644 media: ov2680: Do not fail if data-lanes property is absent
Since commit 63b0cd30b7 ("media: ov2680: Add bus-cfg / endpoint
property verification") the ov2680 driver no longer probes when the
'data-lanes' property is absent.

The OV2680 sensor has only one data lane, so there is no need for
describing it the devicetree.

Remove the unnecessary data-lanes property check.

79d6b42e13 media: imx335: Limit analogue gain value
The sensor gain (both analog and digital) are controlled by a
single gain value where:
- 0dB to 30dB correspond to analog gain
- 30.3dB to 72dB correspond to digital gain
  (with 0.3dB step)

Hence, limit the analogue gain value to 100.
For digital gain, support can be added later if needed.

The imx335 reports a recommended pixel area of - 2592x1944.
The driver supported mode however limits it to height=1940.

Fix the height discrepency by correctly the value of height
(with updates to vblank and mode registers).

The IMX335_REG_HTRIMMING should also be corrected to the start
offset(i.e. 48) instead of chosing a abritrary crop start of 384.

545b215736 media: i2c: et8ek8: Don't strip remove function when driver is builtin
Using __exit for the remove function results in the remove callback
being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.

This also fixes a W=1 modpost warning:

ov2680 1-0036: error -EINVAL: supported link freq 330000000 not found
ov2680 1-0036: probe with driver ov2680 failed with error -22

As the 'link-frequencies' property is not mandatory, allow the probe
to succeed by skipping the link-frequency verification when the
property is absent.

49a9bad83b media: ov2680: Clear the 'ret' variable on success
Since commit 63b0cd30b7 ("media: ov2680: Add bus-cfg / endpoint
property verification") even when the correct 'link-frequencies'
property is passed in the devicetree, the driver fails to probe:

ov2680 1-0036: probe with driver ov2680 failed with error -22

The reason is that the variable 'ret' may contain the -EINVAL value
from a previous assignment:

ret = fwnode_property_read_u32(dev_fwnode(dev), "clock-frequency",
			       &rate);

Fix the problem by clearing 'ret' on the successful path.

Tested on imx7s-warp board with the following devicetree:

port {
	ov2680_to_mipi: endpoint {
		remote-endpoint = <&mipi_from_sensor>;
		clock-lanes = <0>;
		data-lanes = <1>;
		link-frequencies = /bits/ 64 <330000000>;
	};
