+	default y if !EXPERT
+	help
+	   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
+	   needed to support media drivers will be enabled. Also, all
+	   media device drivers should be shown.
+

+	depends on HAS_IOMEM
+	select I2C
+	select I2C_MUX
+	default y if MEDIA_SUPPORT_FILTER
+	help
+	  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.

+	  hybrid analog/digital TV chipset.
+
+	  Note: There are several DVB cards that are based on chips that
+		support both analog and digital TV. Disabling this option
+		will disable support for them.

+	  and don't use PCI, USB or Firewire buses.
+
+	  This is found on Embedded hardware (SoC), on V4L2 codecs and
+	  on some GPU and newer CPU chipsets.
+
+	  Say Y when you want to be able to see such devices.
+
+config MEDIA_TEST_SUPPORT
+	bool
+	prompt "Test drivers" if MEDIA_SUPPORT_FILTER
+	default y if !MEDIA_SUPPORT_FILTER
+	help
+	  These drivers should not be used on production kernels, but
+	  can be useful on debug ones. This option enables several dummy drivers
+	  that simulate real hardware. Very useful to test userspace
+	  applications and to validate if the subsystem core doesn't
+	  have regressions.
+
+	  Say Y if you want to use some virtual test driver.
+
+	  In case of doubts, say N.
+	  Say Y when you have a software defined radio device.
