The only item that opens at the CEC Kconfig menu is related to Remote Controller. Also, its support should not depend on media support, so it makes sense to keep both RC and CEC together. After this change, the main media menus that are visible under "Device Drivers" menu are: <*> Remote Controller support ---> [ ] HDMI CEC RC integration (NEW) < > HDMI CEC drivers <M> Multimedia support ---> Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Configuring the media subsystem can be complex, as there are
|
|
hundreds of drivers and other config options.
|

This menu offers option that will help the Kernel's config
|
|
system to hide drivers that are out of the scope of the
|
|
user needs, and disabling core support for unused APIs.
|

If not selected, all non-optional media core functionality

By default, a media driver auto-selects all possible ancillary
|
|
devices such as tuners, sensors, video encoders/decoders and
|
|
frontends, that are used by any of the supported devices.
|
|
|
|
This is generally the right thing to do, except when there
|
|
are strict constraints with regards to the kernel size,
|
|
like on embedded systems.
|
|
|
|
Use this option with care, as deselecting ancillary drivers which
|
|
are, in fact, necessary will result in the lack of the needed
|
|
functionality for your device (it may not tune or may not have
|
|
the needed demodulators).
|
|
|
|
If unsure say Y.
