cca331a64c media: atomisp: Remove clearing of ISP crop / compose rectangles on file release
There is no need to clear the ISP sink-pad crop and source-pad
compose rectangles  on release of the /dev/video# file.

Both will be reset by atomisp_set_fmt() which is guaranteed to
get called by atomisp_queue_setup() (if not called already)
before another stream starts and thus before these selections
are used again.

Also the file injection support the comment talks about has long
been dropped from the driver.

struct atomisp_platform_data only has a single subdevs member. Remove
this struct and replace atomisp_get_platform_data() with
atomisp_platform_get_subdevs().

Note atomisp_get_platform_data() and now atomisp_platform_get_subdevs()
always succeed, so while at it also remove unnecessary error checking.

Drop the atomisp custom lm3554 flash driver, support for flash drivers
using the custom atomisp flash interface is going to be removed from

If flash supports for the lm3554 turns out to be necessary on some

using the new include/linux/led-class-flash.h APIs.

The atomisp specific lm3554 driver could still be usable as a reference
for how to use / driver the lm3554 for a future re-implementation
using standardized APIs, but for that it can be retrieved from

a0821ca14b media: atomisp: Remove test pattern generator (TPG) support
The TPG support registers a v4l2-subdev for this, but this is not part of
the media-controller graph in any way. After manually selecting the TPG
as input using the s_input ioctl it does not work.

Several supported sensors have their own working TPG and using the sensor's
TPG means that the same data-flow is used as with actual sensors rather
then the quite different data-flow from the ISP's builtin TPG.

Remove the broken TPG support, when a test-pattern is needed for testing
a sensor's TPG can be used. Using a sensor's TPG is actually better for
testing since then the actual normal data-flow is being tested.

e03a5d3e95 media: atomisp: Drop atomisp_pipe_check() from atomisp_link_setup()
The media-controller core (__media_entity_setup_link()) already checks
that the pads of the link are not streaming before calling the setup_link()
pad-op so calling atomisp_pipe_check() is not necessary;

and taking isp->mutex inside the setup_link() pad-op leads to a possible
ABBA deadlock vs the media-device graph_mutex which in the case of
the setup_link() pad-op is taken before calling the op, while in other
scenarios the graph_mutex is taken after the isp->mutex.

52cc673b8d media: atomisp: Propagate set_fmt on sensor results to CSI port
So far the CSI port sink and source pads have not had their fmt set at all,
leaving things at the default of SBGGR8_1X8/0x0.

This means that pipeline validation such as e.g. done when calling
media_pipeline_start() will fail since the links to / from the CSI
ports have different fmts on each end.

Store a pointer to the CSI port v4l2-subdev in struct atomisp_input_subdev,
and use this in atomisp_set_sensor_crop_and_fmt() to propagate the sensors
new fmt after a successful set_fmt to the CSI port it is connected too.

The input->csi_port pointer also allows simplifying atomisp_link_setup().

1a1ce0c308 media: atomisp: Add atomisp_select_input() helper
When switching input/sensor the s_power() callback must be called
for old sensor drivers to power on the new sensor and power off
the previous sensor.

atomisp_s_input() already does this but atomisp_link_setup()
did not do this.

Add a new atomisp_select_input() helper which does this and use this
in both atomisp_s_input() and atomisp_link_setup() for consistent
behavior.

Also make atomisp_link_setup() turn the sensor back off when
a link gets disabled.

61d9b1ffc6 media: atomisp: Turn on sensor power from atomisp_set_fmt()
ATM the atomisp driver does not call s_power() at all when no s_input
ioctl() is done by the application. This breaks older sensor drivers
which rely on s_power() for power-management.

Some drivers have worked around this, e.g. commit c5fafbadae ("media:
atomisp: gc0310: Power on sensor from set_fmt() callback") and
commit b3118a942c ("media: atomisp: ov2722: Power on sensor from
set_fmt() callback"), but this really should be fixed in the atomisp
driver itself, so that all old drivers can work.

A logical place to call s_power() would be from atomisp_start_streaming() /
atomisp_stop_streaming(). But some older drivers, e.g. the atomisp-ov2722
driver already write mode related registers on set_fmt() instead of waiting
on stream on. So the s_power(1) needs to happen at the first set_fmt().

Add an atomisp_s_sensor_power(..., 1) call just before calling set_fmt()
for this. If the power was already enabled through e.g. a s_input ioctl
atomisp_s_sensor_power() will skip calling the s_power() v4l2-subdev-op
a second time.

atomisp_s_sensor_power() helper which takes care of avoiding unbalanced
s_power() subdev calls as well as takes care of handling the special
-ENOIOCTLCMD return for subdevs which don't implement s_power().

Some userspace apps (e.g. libcamera) do not like it if the enum_fmts
ioctl returns the same fmt twice. Drop the second "do not use"
V4L2_PIX_FMT_UYVY entry for parallel sensors to fix this.

The current atomisp code does not support anything other then raw bayer
sensors anyways, so dropping this is not an issue.

faa4364bef media: stk1160: fix bounds checking in stk1160_copy_video()
The subtract in this condition is reversed.  The ->length is the length
of the buffer.  The ->bytesused is how many bytes we have copied thus
far.  When the condition is reversed that means the result of the
subtraction is always negative but since it's unsigned then the result
is a very high positive value.  That means the overflow check is never
true.

Additionally, the ->bytesused doesn't actually work for this purpose
because we're not writing to "buf->mem + buf->bytesused".  Instead, the
math to calculate the destination where we are writing is a bit
involved.  You calculate the number of full lines already written,
multiply by two, skip a line if necessary so that we start on an odd
numbered line, and add the offset into the line.

To fix this buffer overflow, just take the actual destination where we
are writing, if the offset is already out of bounds print an error and
return.  Otherwise, write up to buf->length bytes.

1df7b8cd3a media: videobuf2: improve max_num_buffers sanity checks
Ensure that drivers set max_num_buffers to a value >= 32.
For now there is no reason for drivers to request a lower
limit and doing so might potentially cause userspace issues.
Note that the old check of > MAX_BUFFER_INDEX was pointless
since q->max_num_buffers was already limited to MAX_BUFFER_INDEX
or less.

Also add a sanity check in __vb2_init_fileio(), returning
-ENOSPC if a driver returns more than 32 buffers from
VIDIOC_REQBUFS with count = q->min_reqbufs_allocation.

The vb2_fileio_data struct only supports up to 32 buffers,
so we need a check there.

dd05fd125e media: cec: return -ENODEV instead of -ENXIO if unregistered
If the CEC device is unregistered, then an attempt to open
the device node should result in an -ENODEV error instead of
-ENXIO.

Document this as well in cec-func-open.rst.

This is consistent with the error code returned by other
file operations such as ioctl.

1ed4477f2e media: v4l2-core: hold videodev_lock until dev reg, finishes
After the new V4L2 device node was registered, some additional
initialization was done before the device node was marked as
'registered'. During the time between creating the device node
and marking it as 'registered' it was possible to open the
device node, which would return -ENODEV since the 'registered'
flag was not yet set.

Hold the videodev_lock mutex from just before the device node
is registered until the 'registered' flag is set. Since v4l2_open
will take the same lock, it will wait until this registration
process is finished. This resolves this race condition.

on/off the sensor.

On other ACPI platforms, such as e.g. various HP models with IPU6 +
hi556 sensor, the sensor driver must control the avdd regulator itself.

Add support for having the driver control the sensor's avdd regulator.
Note this relies on the regulator-core providing a dummy regulator
(which it does by default) on platforms where Linux is not aware of
the avdd regulator.
