Subject: [PATCH 6/6] arm64: dts: Add SBA-RAID DT nodes for Stingray SoC
Date: Wed, 26 Jul 2017 11:06:44 +0530 [thread overview]
Message-ID: <1501047404-14456-7-git-send-email-anup.patel@broadcom.com> (raw)
In-Reply-To: <1501047404-14456-1-git-send-email-anup.patel@broadcom.com>
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.
