Instead of having 3 options to allow customizing the media sub-drivers (tuners, I2C drivers, frontends), merge all of them into just one. That simplifies the life for users, as they can just keep this untouched. Life for developers is also simpler, as there's now just one Kconfig item to remember, for the ancillary sub-drivers providing supports for chips that could change from one board design to another.

This option enables DVB Network Support which is a part of the DVB

standard. It is used, for example, by automatic firmware updates used

on Set-Top-Boxes. It can also be used to access the Internet via the

DVB card, if the network provider supports it.

|
By default, a TV driver auto-selects all possible tuners
|
|
thar could be used by the driver.
|
|
|
|
This is generally the right thing to do, except when there
|
|
are strict constraints with regards to the kernel size.
|
|
|
|
Use this option with care, as deselecting tuner drivers which
|
|
are in fact necessary will result in TV devices which cannot
|
|
be tuned due to lack of the tuning driver.
|
|
|
|
If unsure say Y.
