[alsa-devel] [PATCH 6/7] ASoC: kirkwood: allow smaller audio periods and smaller number of periods

[Russell King]

There is no hardware restriction requiring a minimum of 8 periods, or
a minimum of 2048 bytes in a period.  Let's drop these values so that
userspace has more flexibility in choosing these parameters.
