Subject: [PATCH] ASoC: SOF: topology: Add helper function for processing tuple arrays
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: d87524bf9aab511906e7e9bab90198510c28149f
Patch-mainline: v5.18-rc1
References: jsc#PED-850
Add a helper function for processing tuple arrays and populating the
IPC structure objects based on the token ID passed.
Introduce a new enum representing token ID for the tokens
currently used in the topology parse and a new struct sof_token_info
to store the information about a token set. Finally, expose the struct
snd_sof_topology token as it will be used by IPC-specific code.
