98 bool "Media Controller API"
99 depends on MEDIA_CAMERA_SUPPORT || MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT
101 Enable the media controller API used to query media devices internal

104 This API is mostly used by camera interfaces in embedded platforms.

119 DO NOT ENABLE THIS OPTION UNLESS YOU KNOW WHAT YOU'RE DOING.
121 This option enables the Request API for the Media controller and V4L2
122 interfaces. It is currently needed by a few stateless codec drivers.
124 There is currently no intention to provide API or ABI stability for
125 this new API as of yet.

181 This option enables DVB Network Support which is a part of the DVB
182 standard. It is used, for example, by automatic firmware updates used
183 on Set-Top-Boxes. It can also be used to access the Internet via the
184 DVB card, if the network provider supports it.
186 You may want to disable the network support on embedded devices. If

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