[PATCH v2 9/9] ASoC: Intel: avs: Enact power gating policy
Cezary Rojewski
cezary.rojewski at intel.com
Wed Oct 26 15:50:14 CEST 2022
Update all firmware loading functions to also account for the power
gating policy. As module loading routine is missing the chicken bits
manipulation entirely, add the entire set there.
