The media subsystem has hundreds of driver-specific options. The *_SUPPORT config options work as a sort of filter, allowing to reduce its complexity for users that won't want to dig into thousands of options they don't need. Yet, it the filtering options are becoming large. So, let's place it on a sub-menu. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

applications and to validate if the subsystem core is doesn't

have regressions.

|
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.
