[PATCH v4 01/13] ASoC: Intel: Add catpt device
Cezary Rojewski
cezary.rojewski at intel.com
Wed Aug 12 22:57:41 CEST 2020
Declare base structures, registers and device routines for the catpt
solution. Catpt deprecates and is a direct replacement for
sound/soc/intel/haswell. Supports Lynxpoint and Wildcat Point both.
