Subject: [PATCH v2 0/2] dmaengine: omap-dma: Fix cyclic suspend/resume

Hi,

When the audio is paused/resumed (application paused the sream or board suspend)
the audio was only playing back one period worth of data and then stops because
the omap_dam_stop() clears the link configuration and it is not restored in
start.

Also add memory barrier call to resume path since this could happen right after
coming out from suspend.

Regards,
Peter
