Thanks for your suggestions. But this tool is not for directly adding
controls from the user space.
It's for ADSP firmware vendors to describe the controls/widgets/pcms for
a specific version of firmware. Previously, these components are hard
coded in ASoC platforms drivers and not so convenient to share a common
driver for different firmwares. The topology binary generated by this
tool will be loaded by ASoC platform driver with a specific firmware
binary, and so ASoC will create the controls/widgets/pcms that match the
firmware automatically.
Thanks
Mengdong
