Subject: [PATCH 403/432] 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.
