Lukas Bulwahn f7ec3f62d7 media: remove reference to CONFIG_EMBEDDED in MEDIA_SUPPORT_FILTER

The config EMBEDDED selects EXPERT, i.e., when EMBEDDED is enabled, EXPERT
is usually also enabled. Hence, it sufficient to have the option
MEDIA_SUPPORT_FILTER set to y if !EXPERT.

This way, MEDIA_SUPPORT_FILTER does not refer to CONFIG_EMBEDDED anymore
and allows us to remove CONFIG_EMBEDDED in the close future.

Remove the reference to CONFIG_EMBEDDED in MEDIA_SUPPORT_FILTER.

config MEDIA_SUPPORT_FILTER bool "Filter media drivers" 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.

config MEDIA_SUBDRV_AUTOSELECT bool "Autoselect ancillary drivers (tuners, sensors, i2c, spi, frontends)" 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.

  Say Y when you have a TV board with analog support or with a
  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.

config MEDIA_DIGITAL_TV_SUPPORT bool prompt "Digital TV" if MEDIA_SUPPORT_FILTER default y if !MEDIA_SUPPORT_FILTER help Enable digital TV support.

  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.
