media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.
On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

This is a driver for USB devices with the Silicon Labs SI470x

chip. Currently these devices are known to work:
|
|
|
|
|
- 10c4:818a: Silicon Labs USB FM Radio Reference Design
|
|
|
|
|
- 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music)
|
|
|
|
|
- 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
|

|
|
- 10c5:819a: Sanei Electric FM USB Radio (aka DealExtreme.com PCear)
|
|
|
|
|
|
|
|
|
|
Sound is provided by the ALSA USB Audio/MIDI driver. Therefore
|
|
|
|
|
if you don't want to use the device solely for RDS receiving,
|
|
|
|
|
it is recommended to also select SND_USB_AUDIO.
|
|
|
|
|

|
Please have a look at the documentation, especially on how
|
|
|
|
|
to redirect the audio stream from the radio to your sound device:
