Subject: [PATCH] ASoC: tlv320aic32x4: Model BDIV divider in CCF
|
|
|
|
commit 9b484124ebd906c4d6bc826cc0d417e80cc1105c upstream.
|
|
|
|
Model and manage BDIV divider 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.
