[PATCH 1/7] ASoC: SOF: Intel: ICL: move ICL-specific ops to icl.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ranjani Sridharan <ranjani.sridharan@xxxxxxxxxxxxxxx>

Move the ICL specific ops to icl.c. Also introduce a
macro ICL_DSP_HPRO_CORE_ID to define the core that
should be powered up when HPRO is enabled.
