-Subject: [PATCH 407/703] ASoC: tlv320aic32x4: Model DAC/ADC dividers in CCF
-
-commit a51b50062091619915c5155085bbe13a7aca6903 upstream.
-
-Model and manage DAC/ADC dividers as components 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.
