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

39 * We make several passes over the data (since it wont necessarily be ordered)
40 * and process objects in the following order. This guarantees the component
41 * drivers will be ready with any vendor data before the mixers and DAPM objects
42 * are loaded (that may make use of the vendor data).
