In dmaengine context we By BAM_FIFO_SIZE I meant a FIFO depth for hw descriptors, i.e. how many hw descriptors could be pushed into the descriptor FIFO. In our case we wrote BAM_P_FIFO_SIZES register with SZ_32K - 8, which means that the FIFO will be 4095 hw descriptors deep. In fact the important patch in this series 4/5 where I corrected the value we wrote in BAM_P_FIFO_SIZES register. 4/5 and 5/5 can be postponed till we have better decision... -- regards, Stan -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
