[RFC 36/37] ASoC: Intel: avs: SKL-based platforms support
Cezary Rojewski
cezary.rojewski at intel.com
Wed Dec 8 12:13:00 CET 2021
Define handlers specific to cAVS 1.5 platforms, that is SKL, KBL, AML
and all other variants based on this very version of AudioDSP
architecture. Most are specific to SKL-alike platforms with only
skl_log_buffer_offset() being exposed and used later by younger
equivalents.
