+Subject: [PATCH] ASoC: tlv320aic32x4: Break out clock setting into
+ separate function
+
+commit bf31cbfbe25001036e1e096b1c260bf871766ea5 upstream.
+
+Break the clock setting logic out from the main hw_params.  It's
+rather large and unweildy and makes for a large function.  This
+also better enables some of the following changes to the clock
+tree access in the driver.
