I only have schematics for Beagle ... which makes VERY minimal
use of the twl4030 audio capabilities:
- stereo "headset" output, without its mic
- stereo aux-in
Other twl4030 family boards *could* have:
- microphone input for that headset
- stereo "hands-off" speakers
- mono earpiece output
- two other microphone input channels
And maybe more; that's just me summarizing unconnected pins,
not the datasheet. There are also cost-reduced parts with
less audio capability.
I make no claim about audio expertise -- the nearest I come
to it is observing a few years back that there was a huge
framework hole, which ASoC seems to fill -- but I wonder if
it shouldn't suffice just to provide a mask of capabilities
that are wired up on a given board.
