From ba2772edbe1f03a695029ca82844615fe41d28fc Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 13 Aug 2010 19:36:56 +0100 Subject: [PATCH] ASoC: Implement BCLK rate selection for WM8580 Drive a minimal supported number of clocks required for the current bit format in master mode. In slave mode this setting has no effect.
