    Subject[PATCH 6/6] arm64: dts: Add SBA-RAID DT nodes for Stingray SoC
    Date
    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.
