[PATCH v4 0/4] Broadcom SBA RAID support

The Broadcom SBA RAID is a stream-based device which provides RAID5/6 offload. It requires a SoC specific ring manager (such as Broadcom FlexRM ring manager) to provide ring-based programming interface. Due to this, the Broadcom SBA RAID driver (mailbox client) implements DMA device having one
