* Add support to read audio firmware topology alongside firmware text. The
* topology data can contain kcontrols, DAPM graphs, widgets, DAIs, DAI links,
* equalizers, firmware, coefficients etc.
*
* This file only manages the core ALSA and ASoC components, all other bespoke
* firmware topology data is passed to component drivers for bespoke handling.
