Fix the dmaengine API usage by calling dmaengine_synchronize() after dmaengine_terminate_async() when xrun events occur in application 2. Use the McASP AFIFO property from DT to refine the period size, instead of hardcoding minimum to 64 samples Signed-off-by: Jai Luthra --- Changes in v3: - Use sync_stop() hook instead of a prepare() hook for the DMA channel synchronization - Link to v2: https://lore.kernel.org/r/20240610-asoc_next-v2-0-b52aaf5d67c4@ti.com Changes in v2: - Fix compiler warning for prepare callback by marking it static - Pass numevt directly to hw_rule_min_periodsize() - Link to v1: https://lore.kernel.org/r/20240604-asoc_next-v1-0-e895c88e744d@ti.com --- Jai Luthra (2): ALSA: dmaengine: Synchronize dma channel after drop() ASoC: ti: davinci-mcasp: Set min period size using FIFO config include/sound/dmaengine_pcm.h | 1 + sound/core/pcm_dmaengine.c | 10 ++++++++++ sound/soc/soc-generic-dmaengine-pcm.c | 8 ++++++++ sound/soc/ti/davinci-mcasp.c | 9 +++++++-- 4 files changed, 26 insertions(+), 2 deletions(-) --- base-commit: a957267fa7e9159d3d2ee1421359ebf228570c68 change-id: 20240604-asoc_next-c063fcc190c6 Best regards,
