This commit adds DAM controller present on Actions S700, it differs from S900 in terms of number of dma channels and requests. Signed-off-by: Amit Singh Tomar <amittomer25@gmail.com> --- Changes since v2: * added power-domain property as sps is enabled now and DMA needs it. Changes since v1: * No Change.
