The bin-factor-x and bin-factor-y ctrls are only used internally to
get a single value to pass to atomisp_css_input_set_binning_factor(),
which is supposed to tune the lens-shading correction for the binning
factor. But all sensor drivers return either 0 or 1 for this,
with 0 meaning unset and 1 meaning no-binning. Even though some modes
do actually do binning ...
Also note that the removed atomisp_get_sensor_bin_factor() would fall
back to 0 if either the x and y factor differ or if the ctrls are not
implemented (not all sensor drivers implement them).
Simply always pass 0 to atomisp_css_input_set_binning_factor().
This is part of a patch-series which tries to remove atomisp specific /
custom code from the sensor drivers, with as end goal to make the atomisp
drivers regular camera sensor drivers.

This ioctl returns a number of fixed sensor parameters +
a number of mode-specific parameters.
With libcamera these fixed parameters are instead stored in a table
with sensor-name to parameters mappings (camera_sensor_properties.cpp);
and the variable parameters can be derived from the set fmt.
So this custom ioctl is not necessary; and it currently has no users.

On BYT on poweron/runtime-resume the code is doing:
1. Do nothing
2. msleep(10)
3. Start actual poweron sequence
Since the runtime resume can happen at any moment, waiting 10ms
after it does not really make any sense.
According to both the comment and to:

The atomisp does not use standard PCI power-management through the
PCI config space. Instead this driver directly tells the P-Unit to
disable the ISP over the IOSF. The standard PCI subsystem pm_ops will
try to access the config space before (resume) / after (suspend) this
driver has turned the ISP on / off, resulting in the following errors:
Unable to change power state from D0 to D3hot, device inaccessible
Unable to change power state from D3cold to D0, device inaccessible
Getting logged into dmesg a whole bunch of time during boot as well as
every time the camera is used.
To avoid these errors use a custom pm_domain instead of standard driver
pm-callbacks so that all the PCI subsys suspend / resume handling is
skipped and call pci_save_state() / pci_restore_state() ourselves.

The videobuf2-core expects buffers to be put back in the queued state
when the vb2 start_streaming callback fails. But the atomisp
atomisp_flush_video_pipe() would unconditionally return them to the core
in an error state.
This triggers the following warning in the videobuf2-core:
drivers/media/common/videobuf2/videobuf2-core.c:1652:
/*
* If done_list is not empty, then start_streaming() didn't call
* vb2_buffer_done(vb, VB2_BUF_STATE_QUEUED) but STATE_ERROR or

When the ene device is detaching, function ene_remove() will
be called. But there is no function to cancel tx_sim_timer
in ene_remove(), the timer handler ene_tx_irqsim() could race
with ene_remove(). As a result, the UAF bugs could happen,
the process is shown below.
(cleanup routine) | (timer routine)
| mod_timer(&dev->tx_sim_timer, ..)
ene_remove() | (wait a time)
| ene_tx_irqsim()
| dev->hw_lock //USE
| ene_tx_sample(dev) //USE
Fix by adding del_timer_sync(&dev->tx_sim_timer) in ene_remove(),
The tx_sim_timer could stop before ene device is deallocated.
What's more, The rc_unregister_device() and del_timer_sync()
should be called first in ene_remove() and the deallocated
functions such as free_irq(), release_region() and so on
should be called behind them. Because the rc_unregister_device()
is well synchronized. Otherwise, race conditions may happen. The
situations that may lead to race conditions are shown below.
Firstly, the rx receiver is disabled with ene_rx_disable()
before rc_unregister_device() in ene_remove(), which means it
can be enabled again if a process opens /dev/lirc0 between
ene_rx_disable() and rc_unregister_device().
Secondly, the irqaction descriptor is freed by free_irq()
before the rc device is unregistered, which means irqaction
descriptor may be accessed again after it is deallocated.
Thirdly, the timer can call ene_tx_sample() that can write
to the io ports, which means the io ports could be accessed
again after they are deallocated by release_region().
Therefore, the rc_unregister_device() and del_timer_sync()
should be called first in ene_remove().

The Hantro driver uses a hardcoded value for the bus_info field in the
media device and |struct v4l2_capability|. This worked well when there
was just one device. However with the iMX.8 series we are now seeing
two Hantro blocks on the same chip. The static bus_info is no longer
sufficient for differentiating devices.
Since commit f2d8b6917f ("media: v4l: ioctl: Set bus_info in
v4l_querycap()"), the V4L2 core provides a default value for the
bus_info field for platform and PCI devices. This value will match
the default value for media devices added by commit cef699749f
("media: mc: Set bus_info in media_device_init()"). These defaults
are stable and device-specific.
Drop the static bus_info values from the hantro driver and use the
defaults.
