[alsa-devel] [PATCH 13/17] ASoC: tegra: set a sensible initial clock rate

From: Stephen Warren <swarren at nvidia.com>

Initialize the audio clock tree appropriately for some reasonable rate.
This makes sure the PLLs etc. are actually programmed to something
reasonable when the audio driver is loaded.
