[media] cec: select CEC_CORE instead of depend on it

2017-06-04T18:23:33+00:00

The CEC framework is used by both drm and media. That makes it tricky
to get the dependencies right.

This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options
out of the media menu and instead drivers that want to use CEC should
select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

[media] cec: Kconfig cleanup

2017-04-19T09:50:52+00:00

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.

[media] media: add CEC notifier support

2017-04-10T15:48:28+00:00

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.

[media] cec: move the CEC framework out of staging and to media

2016-11-16T17:40:20+00:00

The last open issues have been addressed, so it is time to move
this out of staging and into the mainline and to move the public
cec headers to include/uapi/linux.

[media] Add GS1662 driver, a video serializer

2016-09-19T17:36:24+00:00

You can read datasheet here:
http://www.c-dis.net/media/871/GS1662_Datasheet.pdf

It's a component which supports HD and SD CEA or SDI formats
to SDI output. It's configured through SPI bus.

GS1662 driver is implemented as v4l2 subdev.

[media] cec: fix Kconfig dependency problems

2016-07-08T21:34:00+00:00

- Use IS_REACHABLE(RC_CORE) instead of IS_ENABLED: if cec is built-in and
  RC_CORE is a module, then CEC can't reach the RC symbols.
- Both cec and cec-edid should be bool and use the same build 'mode' as
  MEDIA_SUPPORT (just as is done for the media controller code).
- Add a note to staging that this should be changed once the cec framework
  is moved out of staging.

[media] cec-edid: add module for EDID CEC helper functions

2016-06-28T12:45:51+00:00

The cec-edid module contains helper functions to find and manipulate
the CEC physical address inside an EDID. Even if the CEC support itself
is disabled, drivers will still need these functions. Which is the
reason this is module is separate from the upcoming CEC framework.

[media] bq/c-qcam, w9966, pms: move to staging in preparation for removal

2014-12-17T01:21:44+00:00

These drivers haven't been tested in a long, long time. The hardware is
ancient and hopelessly obsolete. These drivers also need to be converted
to newer media frameworks but due to the lack of hardware that's going
to be impossible. In addition, cheaper and vastly better hardware is
available today.

So these drivers are a prime candidate for removal. If someone is
interested in working on these drivers to prevent their removal, then
please contact the linux-media mailinglist.

Let's be honest, the age of parallel port webcams and ISA video capture
boards is really gone.

[media] move i2c files into drivers/media/i2c

2012-09-06T21:42:54+00:00

Based on a patch from Sylvester Nawrocki

This fixes regression introduced with commmit cb7a01ac324bf2ee2,
"[media] move i2c files into drivers/media/i2c".

The linked order affect what drivers will be initialized first, when
they're built-in at Kernel. While there are macros that allow changing
the init order, like subsys_initcall(), late_initcall() & friends,
when all drivers  linked belong to the same subsystem, it is easier
to change the order at the Makefile.

All I2C modules must be linked before any drivers that actually use it,
in order to ensure proper module initialization order.

Also, the core drivers should be initialized before the drivers that use
them.

This patch reorders the drivers init, in order to fulfill the above
requirements.

[media] rename drivers/media/video as .../platform

2012-08-15T19:43:09+00:00

The remaining drivers are mostly platform drivers. Name the
dir to reflect it.

It makes sense to latter break it into a few other dirs.
