[alsa-devel] [PATCH v2 09/10] ASoC: topology: Change stream formats to bitwise flag

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

The toplogy user space tool will generate this bitwise flag by using
SNDRV_PCM_FORMAT_* exposed by asound.h, and the topology core will copy
this flag when generating DAI streams.
