This is the point. Why write a card driver? For example audio over MOST or
for HDMI audio?
Or when I have some utility in userspace to test the functionality.
Wont it be better to atleast enumerate the driver and show the capabilities
This can help in many phases of design like emulation, bringup (doing
loopback between 2 interfaces at SOC level)?
So far I have been using ALSA for the userspace utilites it supports
(alsalib), for codec support I dont feel need that
its absolutely needed (spdif/hdmi for instance) and this can be applied to
even other machine drivers.
Cant we have support for all this, if not codec, somewhere else?
