Oh nice. So the Droid 4 hardware wiring looks like this (at least
according to my understanding):
+----------+ +-------------+
| OMAP4 | | CPCAP |
| | | |
| [McBSP2] | <-----> | [HiFi DAI] |
| | | |
| [McBSP3] | <--+--> | [Voice DAI] |
| | | | |
+----------+ | +-------------+
|
+----------+ | +-------------+
| MDM6600 | | | WL1285 |
| | | | |
| [DAI] | <--+--> | [DAI] |
| | | |
+----------+ +-------------+
Legend:
OMAP4 = SoC running Linux
CPCAP = Audio codec
MDM6600 = Baseband
WL1285 = Bluetooth
Re-reading the audio-graph-card binding document I still don't see
how the network (OMAP.McBSP3, CPCAP.Voice, MDM6600, WL1285) is
supposed to look like. It seems to expect point-to-point DAI
connections.
