From a622251c01b628cbbd1b02a877a6469303ec2b58 Mon Sep 17 00:00:00 2001 From: Russell King <rmk+kernel@arm.linux.org.uk> Date: Thu, 26 Jun 2014 15:23:15 +0100 Subject: [PATCH] ASoC: kirkwood: allow smaller audio periods and smaller number of periods 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.
