From e22579713ae1384a3dff545369cebe42b01370fa Mon Sep 17 00:00:00 2001 From: Arnaud Pouliquen Date: Fri, 5 Jun 2015 10:19:06 +0200 Subject: [PATCH] ASoC: simple card: set cpu-dai sysclk with mclk-fs Allows to request a specific mclk frequency per cpu_dai. To support some codecs with mclk provided by the cpu_dai, the mclk rate must be set depending on frame rate.
