From: Mengdong Lin <mengdong.lin at linux.intel.com>

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 just include these conf files of components, and trigger enable/
disable sequence defined by the component devices.

Component devices will not be exposed to applications for backward
compatibility. So audio servers like PulseAudio and CRAS still only see
the machine devices.

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
