After removing the flash support frame_status now always is
ATOMISP_FRAME_STATUS_OK aka 0. Drop frame_status tracking.
This also means one less atomisp custom use for the vb2_buffer->reserved*
fields (all custom use of these fields should be removed).
While at it also remove the no longer used vf_frame pointer from
struct atomisp_sub_device.

Remove the custom flash handling from the atomisp driver. There are
only few Bay Trail / Cherry Trail devices with flash and if those will
ever get supported then this should be done through the new standard
include/linux/led-class-flash.h APIs instead of with atomisp specific
custom APIs.

Drop all ISP controls and ioctls which just get passed through
to the camera subdev. Instead these calls should be done directly
at the sensor subdev.

Remove the custom VCM handling, instead the VCM should be controlled
through its own v4l2-subdev and the new ipu-bridge.c code already
supports instantiating an i2c_client for this and setting up
the necessary endpoints in the fwnode graph.

Remove the support to update a V4L2_CID_RUN_MODE run-mode control
on sensors when changing the atomisp run-mode or directly by calling
the custom ATOMISP_IOC_S_SENSOR_RUNMODE IOCTL.
No sensor drivers implement this and having custom controls / IOCTLs
is undesirable.
Even if there was such a control on sensors then userspace should directly
talk to the sensor v4l2-subdev, rather than relying on a custom IOCTLs
on the output /dev/video# node to pass this through to the senor.

Remove a bunch of sensor related custom IOCTLs because:
1. They are custom IOCTLs and all custom IOCTLs should be removed
2. Userspace should directly talk to the sensor v4l2-subdev, rather
then relying on ioctl-s on the output /dev/video# node to pass
through ioctl-s to the senor
3. Some of these rely on the atomisp specific camera_mipi_info struct
which is going away as we are switching to using standard v4l2
sensor drivers
4. In the case of ATOMISP_IOC_S_EXPOSURE_WINDOW this was using the
v4l2-subdev set_selection API in an undocumented atomisp custom way

Since we no longer support Continuous mode, setting the run_mode to
ATOMISP_RUN_MODE_CONTINUOUS_CAPTURE no longer make sense, so remove
this.
While at it, also remove ATOMISP_RUN_MODE_SDV, which was never exposed
to userspace in the first place.

The custom V4L2_CID_FMT_AUTO control, which defaults to true
controls whether the atomisp driver will automatically configure
the sensor and ISP settings to match.
This is necessary to make normal v4l2 apps to work. We do eventually
want to add libcamera support, but even then moving this to userspace
does not give any added value, while breaking classic v4l2 apps.
Moreover we really don't know all the exact pipeline constraints,
so moving this to userspace/libcamera will be tricky thus it is best
to keep the current in kernel code for this and make the kernel
unconditionally do this.

Continues mode is a special mode where 2 /dev/video devices can be active
at the same time. Either the video-preview + video nodes or the
viewfinder (for still capture) + capture nodes.
For the video-preview + video-recording case modern userspace will
use a single stream multiplexed by pipewire.
The still-capture case is extra special only starting the preview
stream and then relying on a custom ATOMISP_IOC_S_CONT_CAPTURE_CONFIG
ioctl to set things up followed by a second stream on to capture
the amount of configured still pictures. While running the sensor
at full resolution all the time. This case too is better handled
with dma-buf + GPU downscaling for the view-finder rather then all this
custom special code. Besises this the ioctl expects a bunch of special
non error checked conditions to be met otherwise things will crash/hang.
The continues mode also involves a special cases all over the code
getting in the way of further cleanups and simplifying the code to
using just 1 /dev/video# node. So lets remove it and the
related custom ATOMISP_IOC_S_CONT_CAPTURE_CONFIG ioctl.

Remove support for depth mode. This is a special mode where 2 streams
(from 2 different sensors) can be setup and then starting/stopping
1 will automatically also start/stop the other.
Like many of these special features I'm pretty sure that if the queue
setup is not done exactly right things will crash and there is no error
checking for this.
This seems to be for stereoscopic vision and the only known hw which
actually supports this is the Intel Aero board/SDK, all other 1000+
BYT/CHT models don't need this.
This false outside of the standard webcam use scenario which we are
trying to get working and this involves a bunch of hacks / special
exceptions all over the code, so lets remove this.

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.
Remove the ioctl and all the sensor drivers xxxx_get_intg_factor()
helpers which return this info.

These ioctls allow userspace to load custom programs into the ISP, which:
a) Seems dangerous
b) Cannot be used by opensource userspace since there is no FOSS code to
create such programs
b) These seem to be unused even by the Android closed source camera code
(they don't show up in a strace of the camera app)
So removing these seems be a good idea. Another reason to remove these is
that atomisp_acc_map() is the only user of the userptr functionality in
hmm_alloc(), so it gets in the way of further cleanups / simplification
of the hmm code.

The atomisp driver has a long list of todo items and little has been done
to address these lately while more has been added. The driver is also not
functional. In other words, the driver would not be getting out of staging
in the foreseeable future. At the same time it consumes developer
resources in order to maintain the flaky code base. Remove it.

This patch adds support for the Intel IPU v2 as found on Android and IoT
Baytrail-T and Baytrail-CR platforms (those with the IPU PCI mapped). You
will also need the firmware files from your device (Android usually puts
them into /etc) - or you can find them in the downloadable restore/upgrade
kits if you blew them away for some reason.
It may be possible to extend the driver to handle the BYT/T windows
platforms such as the ASUS T100TA. These platforms don't expose the IPU via
the PCI interface but via ACPI buried in the GPU description and with the
camera information somewhere unknown so would need a platform driver
interface adding to the codebase *IFF* the firmware works on such devices.
To get good results you also need a suitable support library such as
libxcam. The camera is intended to be driven from Android so it has a lot of
features that many desktop apps don't fully spport.
In theory all the pieces are there to build it with -DISP2401 and some
differing files to get CherryTrail/T support, but unifying the drivers
properlly is a work in progress.
The IPU driver represents the work of a lot of people within Intel over many
years. It's historical goal was portability rather than Linux upstream. Any
queries about the upstream aimed driver should be sent to me not to the
original authors.
