In this case really it is a boolean indicating if the
corresponding output is mono or not. It is handled thusly in the
code:

		if (arizona->pdata.out_mono[i])
			val = ARIZONA_OUT1_MONO;
		else
			val = 0;

Perhaps some further wording tweaks on the Documentation patch
would be appropriate, but certainly I am happy enough with the
binding.

Thanks,
