Here the trouble in making it DAPM based is that there is no separate
control for AIF input and output. It is confirmed that AIF_EN is the
master control bit, which enables both output as well as input. The AIF
_OE bit is redundant. If we use the same control bit(i.e AIF_EN) for
both DAPM_AIF_IN and DAPM_AIF_OUT, there will be obvious side effects.
Is there any other way to take care of this? Or should we leave it
outside DAPM?
