Sound cards are defined by machines. And off-soc codecs and DSPs embedded in DSP can be taken as the components and resued by different machines/ sound cards. This series allows codec and SOC vendors to install UCM configuration files for a specific codec or DSP, and sound card verb files can include these conf files of components.
Component devices will not be exposed to applications for backward compatibility. So audio servers like PulseAudio and CRAS still only see the machine devices.
History: v2: Use an array to define component directories. Document syntax to enable/disable a component device. Hide cdev defined by the parent device in ucm manager for executing a component sequence.
Mengdong Lin (3): ucm: Skip component directories when scanning sound card configuration files ucm: Parse sequence of component devices ucm: Execute sequence of component devices
