[PATCH v4 0/5] dma: mxs-dma bugfixes and cleanup

[Markus Pargmann]

Hi,

v4 adds another patch to increase sound stability. Patch 3 ("dma: mxs-dma: Fix
channel reset hardware bug") decreases the number of channel stalls, but after
hours of repeated playback the bug still appears. The new patch ("dma: mxs: Use
semaphores for cyclic DMA") replaces reset channel usage with hardware
semaphore counter mechanism.

Regards,

Markus Pargmann
