Include test_drivers/Kconfig when MEDIA_TEST_SUPPORT is enabled rather
than MEDIA_PLATFORM_SUPPORT. Test drivers should not depend on
platform drivers to be enabled.

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.

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.

can be useful on debug ones. It enables several dummy drivers

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

have regressions.
