From ef473fee67f88c0032eb5e55d940b81b08c0ee89 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 23 Sep 2011 16:05:00 +0100 Subject: [PATCH] ASoC: Support a wider range of sample rates on Speyside WM8962 As we've only got one audio interface and it is symmetric we can just set SYSCLK based on the sample rate requested by the application layer. Provide a default so bypass paths work before audio playback.
