I do understand there may be SoCs requiring sophisticated extra audio nodes, but Marvell SoCs don't. I prefer having a single node for the i2s controller *and* exploit the audio subsystem properties from that.
It's not about SoCs, it's about the board. The audio fabric on a board can easily get complex enough to require its own driver. Speakers, mics, jacks and jack detection, external amplifiers, bluetooth, baseband, multiple CODECs. That's what the audio node describes.
Exactly - as I said earlier on this week the issue is that in many cases there is enough going on in audio system design to make the PCB an interesting bit of hardware that's worth describing in the device tree.
To repeat what I said before *please* go back and check the list archives, we've been through this several times.
