I once used letter "/", but then it failed to create the corresponding
debugfs directory... :)
Oh, btw: There are another register that's related to volume control,
it's before DAC (not added in this patchset yet, for simplicity, will
add it later). so the connection looks something like this:
[volume gain A] --> [DAC] --> [Mixer Volume] -> [Output Pins]
Which volume control should be the master volume? I'm a bit unclear on
this one.
