I don't see that. Some people might want to be able to use multichannel on RPi, but that's something very different than adding code that just lies about driver capabilites.
I am going to invite you over for dinner to eat steamed vegetables :) If I make the steamed vegetables in the microwave and they taste like steamed vegetables, are they steamed vegetables ?
If you connect an amplifier with a volume control to your soundcard does that mean that your soundcard now has a volume control? No, your amp has.
I have a bcm2835 (Pi 2 and 3) SoC here. It is producing multichannel (8 out, 6 in) audio. In ALSA we call that DSP mode - right ?!
No. DSP modes are protocol/timing specifications as I2S, PDP, S/PDIF, ... You can look these up in datasheets and if a chip implements such a protocol you can be sure that it adheres to that standard - i.e. it will sync the frames to the pulses on LRclk.
I agree with the thoughts in this thread really if the AP doesn't actually support DSP A mode we shouldn't add DSP A mode.
