+Subject: [PATCH] ASoC: tlv320aic32x4: Model PLL in CCF
+
+commit 514b044cba667e4b7c383ec79b42b997e624b91d upstream.
+
+Model and manage the on-board PLL as a component in the Core
+Clock Framework. This should allow us to do some more complex
+clock management and power control. Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.
