[alsa-devel] [PATCH 5/8] ASoC: topology: ABI - Change stream formats to a 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.
