Some users have been having a hard time finding the hidden menus. A typically case are camera sensor drivers (e.g IMX219, OV5645, etc), which are common on embedded platforms and not really "ancillary" devices. The problem with MEDIA_SUBDRV_AUTOSELECT seems to be related to the fact that it uses the "visible" syntax to hide the menus. This is not obvious and it normally takes some time to figure out. To fix the problem, add a comment on each of hidden menus, which should clarify what option is causing menus to be hidden.

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.
