From: Anup Patel <anup.patel@xxxxxxxxxxxx>
This patch adds Broadcom SBA-RAID DT nodes for Stingray SoC.
The Stingray SoC has total 32 SBA-RAID FlexRM rings and it has
8 CPUs so we create 8 SBA-RAID instances (one for each CPU).
This way Linux DMAENGINE will have one SBA-RAID DMA device for
each CPU.
