[alsa-devel] [PATCH] ASoC: Raise Speyside audio system clock rate to 512fs

Mark Brown broonie at opensource.wolfsonmicro.com
Sun Dec 11 04:54:27 CET 2011


To support advanced system functionality for additional components; the
actively used clocks will remain the same for current components. Also
factor the rate out to a single #define while we're at it.
