-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.
