[alsa-devel] [PATCH v2 1/2] ASoC: SOF: define INFO_ flags in dsp_ops

Pierre-Louis Bossart pierre-louis.bossart at linux.intel.com
Thu Oct 24 23:03:17 CEST 2019


Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined
in the SOF PCM core, which doesn't scale. To account for platform
variations, these flags need to be set in DSP ops.

This patch only moves the definitions and does not change any
functionality.
