Subject: [PATCH 11/14] ASoC: Intel: avs: Path state management
Date: Mon, 28 Mar 2022 19:24:07 +0200	[thread overview]
Message-ID: <20220328172410.761309-12-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20220328172410.761309-1-cezary.rojewski@intel.com>

Add functions to ease with state changing of all objects found in the
path. Each represents either a BIND/UNBIND or SET_PIPELINE_STATE IPC.

DSP pipelines follow simple state machine scheme:
CREATE -> RESET -> PAUSE -> RUNNING -> PAUSE -> RESET -> DELETE

There is no STOP, PAUSE serves that purpose instead.
