media: ti: j721e-csi2rx: Support multiple pixels per clock
Add support for negotiating the highest possible pixel mode (from
single, dual, quad) with the Cadence CSI2RX bridge. This is required to
drain the Cadence stream FIFOs without overflowing when the source is
operating at a high link-frequency [1].
Also, update the Kconfig as this introduces a hard build-time dependency
on the Cadence CSI2RX driver, even for a COMPILE_TEST.

media: cadence: cdns-csi2rx: Support multiple pixels per clock cycle
The output pixel interface is a parallel bus (32 bits), which
supports sending multiple pixels (1, 2 or 4) per clock cycle for
smaller pixel widths like RAW8-RAW16.
Dual-pixel and Quad-pixel modes can be a requirement if the export rate
of the Cadence IP in Single-pixel mode maxes out before the maximum
supported DPHY-RX frequency, which is the case with TI's integration of
this IP [1].
So, we export a function that lets the downstream hardware block request
a higher pixel-per-clock on a particular output pad.
We check if we can support the requested pixels per clock given the
known maximum for the currently configured format. If not, we set it
to the highest feasible value and return this value to the caller.

media: ti: j721e-csi2rx: Fix source subdev link creation
We don't use OF ports and remote-endpoints to connect the CSI2RX bridge
and this device in the device tree, thus it is wrong to use
v4l2_create_fwnode_links_to_pad() to create the media graph link between
the two.
It works out on accident, as neither the source nor the sink implement
the .get_fwnode_pad() callback, and the framework helper falls back on
using the first source and sink pads to create the link between them.
Instead, manually create the media link from the first source pad of the
bridge to the first sink pad of the J721E CSI2RX.

This can be undesirable e.g. in a calibration usecase where the user

Under the condition that the width & height of the cropped image area
does not change, the changed cropping configuration can be applied to
the pixel-array immediately without disturbing the IFP.
Call mt9m114_configure_pa() in mt9m114_pa_set_selection() if the sensor is
in streaming state and the size of the cropping rectangle didn't change,

syzbot is reporting that imon has three problems which result in
hung tasks due to forever holding device lock [1].
First problem is that when usb_rx_callback_intf0() once got -EPROTO error
after ictx->dev_present_intf0 became true, usb_rx_callback_intf0()
resubmits urb after printk(), and resubmitted urb causes
usb_rx_callback_intf0() to again get -EPROTO error. This results in
printk() flooding (RCU stalls).
Alan Stern commented [2] that
In theory it's okay to resubmit _if_ the driver has a robust
error-recovery scheme (such as giving up after some fixed limit on the
number of errors or after some fixed time has elapsed, perhaps with a
time delay to prevent a flood of errors). Most drivers don't bother to
do this; they simply give up right away. This makes them more
vulnerable to short-term noise interference during USB transfers, but in
reality such interference is quite rare. There's nothing really wrong
with giving up right away.
but imon has a poor error-recovery scheme which just retries forever;
this behavior should be fixed.
Since I'm not sure whether it is safe for imon users to give up upon any
error code, this patch takes care of only union of error codes chosen from
modules in drivers/media/rc/ directory which handle -EPROTO error (i.e.
ir_toy, mceusb and igorplugusb).
Second problem is that when usb_rx_callback_intf0() once got -EPROTO error
before ictx->dev_present_intf0 becomes true, usb_rx_callback_intf0() always
resubmits urb due to commit 8791d63af0cf ("[media] imon: don't wedge
hardware after early callbacks"). Move the ictx->dev_present_intf0 test
introduced by commit 6f6b90c9231a ("[media] imon: don't parse scancodes
until intf configured") to immediately before imon_incoming_packet(), or
the first problem explained above happens without printk() flooding (i.e.
hung task).
Third problem is that when usb_rx_callback_intf0() is not called for some
reason (e.g. flaky hardware; the reproducer for this problem sometimes
prevents usb_rx_callback_intf0() from being called),
wait_for_completion_interruptible() in send_packet() never returns (i.e.
hung task). As a workaround for such situation, change send_packet() to
wait for completion with timeout of 10 seconds.

media: v4l2-common: Add a helper for obtaining the clock producer
Introduce a helper for v4l2 sensor drivers on both DT- and ACPI-based
platforms to retrieve a reference to the clock producer from firmware.
This helper behaves the same as devm_clk_get() except where there is
no clock producer like in ACPI-based platforms.
For ACPI-based platforms the function will read the "clock-frequency"
ACPI _DSD property and register a fixed frequency clock with the frequency
indicated in the property.
This function also handles the special ACPI-based system case where:
. The clock-frequency _DSD property is present.
. A reference to the clock producer is present, where the clock is provided
by a camera sensor PMIC driver (e.g. int3472/tps68470.c)
In this case try to set the clock-frequency value to the provided clock.

The second argument to the ioctl handlers is not a file handle any more.
The standard practice is to name it 'void *priv' in drivers. Many

Replace those more exotic names with 'void *priv' in all media staging
