Subject: [PATCH v3 9/9] ASoC: Intel: avs: Enact power gating policy
Date: Thu, 27 Oct 2022 10:23:31 +0200	[thread overview]
Message-ID: <20221027082331.1561740-10-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20221027082331.1561740-1-cezary.rojewski@intel.com>

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.
