Hans Verkuil f9f314f323 [media] media/cec.h: use IS_REACHABLE instead of IS_ENABLED
Fix messages like this:

adv7842.c:(.text+0x2edadd): undefined reference to `cec_unregister_adapter'

when CEC_CORE=m but the driver including media/cec.h is built-in. In that case
the static inlines provided in media/cec.h should be used by that driver.

Fix a link error in this specific combination of config options:

The version below seems to work, though I don't particularly
like the IS_REACHABLE() addition since that can be confusing
to users.

Hans Verkuil e94c32818d [media] cec: rename MEDIA_CEC_NOTIFIER to CEC_NOTIFIER
This config option is strictly speaking independent of the
media subsystem since it can be used by drm as well.

Besides, it looks odd when drivers select CEC_CORE and
MEDIA_CEC_NOTIFIER, that's inconsistent naming.

Hans Verkuil 56a263aaa0 [media] cec: Kconfig cleanup
The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

Add support for CEC notifiers, which is used to convey CEC physical address
information from video drivers to their CEC counterpart driver(s).

Based on an earlier version from Russell King:

https://patchwork.kernel.org/patch/9277043/

The cec_notifier is a reference counted object containing the CEC physical address
state of a video device.

When a new notifier is registered the current state will be reported to
that notifier at registration time.

The interface to configure the LIF in the VSP1 requires adapting the
function prototype for any changes. This makes extending the interface
difficult.

Change the function prototype to pass a structure which can be easily
extended.

This changes the means of disabling the pipeline, by now passing a NULL
configuration rather than passing either a 0 width or height.

Shuah Khan 90cd366bc6 [media] media: Protect enable_source and disable_source handler code paths
Drivers might try to access and run enable_source and disable_source
handlers when the driver that implements these handlers is clearing
the handlers during its unregister.

Fix the following race condition:

process 1				process 2

request video streaming			unbind au0828
v4l2 checks if tuner is free
...					...

					au0828_unregister_media_device()
...					...
					(doesn't hold graph_mutex)
					mdev->enable_source = NULL;
if (mdev && mdev->enable_source)	mdev->disable_source = NULL;
	mdev->enable_source()
(enable_source holds graph_mutex)

As shown above enable_source check is done without holding the graph_mutex.
If unbind happens to be in progress, au0828 could clear enable_source and
disable_source handlers leading to null pointer de-reference.

Fix it by protecting enable_source and disable_source set and clear and
protecting enable_source and disable_source handler access and the call
itself.

process 1				process 2

request video streaming			unbind au0828
v4l2 checks if tuner is free
...					...

					au0828_unregister_media_device()
...					...
					(hold graph_mutex while clearing)
					mdev->enable_source = NULL;
if (mdev)				mdev->disable_source = NULL;
(hold graph_mutex to check and
 call enable_source)
    if (mdev->enable_source)
	mdev->enable_source()

If graph_mutex is held to just heck for handler being null and needs to be
released before calling the handler, there will be another window for the
handlers to be cleared. Hence, enable_source and disable_source handlers
no longer hold the graph_mutex and expect callers to hold it to avoid
forcing them release the graph_mutex before calling the handlers.

IR raw transmitter driver type is specified in the enum
rc_driver_type as RC_DRIVER_IR_RAW_TX which includes all those
devices that transmit raw stream of bit to a receiver.

The data are provided by userspace applications, therefore they
don't need any input device allocation, but still they need to be
registered as raw devices.

Andi Shyti 0f7499fddb [media] rc-main: assign driver type during allocation
The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.

This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.

Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

James Hogan f423ccc1a3 [media] rc: rc-core: Add support for encode_wakeup drivers
Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true and
rc_dev::allowed_wakeup_protocols should be set to the raw IR encoders.

We also do not permit the mask to be set as we cannot generate IR
which would match that.

Sean Young 0751d33c27 [media] rc: change wakeup_protocols to list all protocol variants
For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.

In addition, we need to know the specific variant of the protocol.

In short, these changes are made to the wakeup_protocols sysfs entry:
 - list all the protocol variants rather than the protocol groups,
   e.g. "nec nec-x nec-32" rather than just "nec".
 - only allow one protocol variant to be selected rather than multiple
 - wakeup_filter can only be set once a protocol has been selected in
   wakeup_protocols.

This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.

Sakari Ailus 20b8522736 [media] media: Rename graph and pipeline structs and functions
The media_entity_pipeline_start() and media_entity_pipeline_stop()
functions are renamed as media_pipeline_start() and media_pipeline_stop(),
respectively. The reason is two-fold: the pipeline struct is, rightly,
already called media_pipeline (rather than media_entity_pipeline) and what
this really is about is a pipeline. A pipeline consists of entities ---
and, well, other objects embedded in these entities.

As the pipeline object will be in the future moved from entities to pads
in order to support multiple pipelines through a single entity, do the
renaming now.

Similarly, functions operating on struct media_entity_graph as well as the
struct itself are renamed by dropping the "entity_" part from the prefix
of the function family and the data structure. The graph traversal which
is what the functions are about is not specifically about entities only
and will operate on pads for the same reason as the media pipeline.

The patch has been generated using the following command:

git grep -l media_entity |xargs perl -i -pe '
	s/media_entity_pipeline/media_pipeline/g;
	s/media_entity_graph/media_graph/g'

And a few manual edits related to line start alignment and line wrapping.

This change makes the framework consistent with other frameworks where the

Mauro Carvalho Chehab a41231d52f [media] v4l2-common: add a debug macro to be used with dev_foo()
Currently, there's a mess at the V4L2 printk macros: some drivers
use their own macros, others use pr_foo() or v4l_foo() macros,
while more modern drivers use dev_foo() macros.

The best is to get rid of v4l_foo() macros, as they can be
replaced by either dev_foo() or pr_foo(). Yet, such change can
be disruptive, as dev_foo() cannot use KERN_CONT. So, the best
is to do such change driver by driver.

There are replacements for most v4l_foo() macros, but it lacks
a way to enable debug messages per level. So, add such macro,
in order to make the conversion easier.

In addition devm_rc_allocate_device sets rc->dev.parent as having a
