From 2942a0e285c46587a1025f12597df63ec04d08c6 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 22 May 2014 17:31:49 +0200 Subject: ASoC: simple-card: Support setting mclk via a fixed factor Some platforms require that the codecs mclk is a fixed multiplication factor of the audio stream rate. Add a optional property to the binding to hold this factor and implement a hw_params() function to make use of it.
