Hi,
I'm studying the transition of my ALSA Driver for TI WL1273 BT/FM into ASoC, and I have a question.
Take a look at sound/soc/codecs/wl1273.c You might need the v4l2 and the MFD parts for the wl1273.
The ALSA driver already developped provided one sound card with 2 PCM devices: - PCM devices: BT (capture + playback)
- FM (capture).
These 2 devices are exclusive.
The driver in upstream at the moment handle only one DAI from the wl1273 (the shared BT/FM dai). wl1273 actually have 2 DAI, but the dedicated FM DAI support is not implemented. The codec driver can handle: BT playback/capture (full duplex) FM playback/capture (half duplex) Since it is using the same DAI, BT and FM (audio) can not be used at the same time.
