This is the core of the WL1273 FM radio driver, it connects the two child modules. The two child drivers are drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c. The radio-wl1273 driver implements the V4L2 interface and communicates with the device. The ALSA codec offers digital audio, without it only analog audio is available. Signed-off-by: Matti J.
