[PATCH v3 0/2] Fixes for McASP and dmaengine_pcm

From: Jai Luthra
Date: Tue Jun 11 2024 - 08:37:15 EST


This series fixes two patches:

1. 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
