Hello! This series contain free running cyclic transfer implementation for pl330. It affect ALL chips using pl330 (not only rockchip) and allow to run cyclic transfers without CPU intervention. As a result it fix sound clicks (observed and not yet observed) because sound clicks must be heard under heavy system load due to the way how cyclic transfers implemented now for pl330. My previous series[1] doesn't get enough attention (no one except me tested it). And it don't get upstream: > 8-03-2016, 6:03, Vinod Koul <vinod.koul@xxxxxxxxx> *: >Overall this series looks okay, but can someone test this. I would not like pl330 to be broken again Now I was asked about the series[1] again by guys from Rockchip, so I send rebased against 4.10.10 version. Hope, someone might test it and confirm that patches work fine. Regards, Alexander.
