In the 5.7 merge window the media kconfig was restructued. For most
platforms these changes set CONFIG_MEDIA_SUPPORT_FILTER=y which keeps
unwanted drivers disabled.

The exception is if a config sets EMBEDDED or EXPERT (see b0cd4fb27665).
In that case the filter is set to =n, causing a bunch of DVB tuner drivers
(MEDIA_TUNER_*) to be accidentally enabled. This was noticed as it blew
out the build time for the Aspeed defconfigs.

Enabling the filter means the Aspeed config also needs to set
CONFIG_MEDIA_PLATFORM_SUPPORT=y in order to have the CONFIG_VIDEO_ASPEED
driver enabled.

Fixes: 06b93644f4d1 ("media: Kconfig: add an option to filter in/out platform drivers")
Fixes: b0cd4fb27665 ("media: Kconfig: on !EMBEDDED && !EXPERT, enable driver filtering")

Another solution would be to revert b0cd4fb27665 ("media: Kconfig: on
!EMBEDDED && !EXPERT, enable driver filtering"). I assume this was done
to be helpful, but in practice it has enabled the TUNER drivers (and
others) for the following configs that didn't have them before:

$ git grep -lE "(CONFIG_EXPERT|CONFIG_EMBEDDED)"  arch/*/configs/ | xargs grep -l MEDIA_SUPPORT

I've cc'd the maintainers of these defconfigs so they are aware.

Mauro, did you have any thoughts here?

Otherwise I'll merge the fix for the aspeed configs for 5.10.

Cheers,

Joel
