[PATCH v2 13/18] ASoC: SOF: Add a tuples array to struct snd_sof_widget

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add 2 new fields to snd_sof_widget to store an array of tuples
defined by struct snd_sof_tuple and the number of tuples. When the
topology gets parsed, the tuples associated with a widget will be stored
in this array and will be used to construct the IPC structure
depending on the IPC version.
