Subject: [PATCH 5/7] arm64: allwinner: a64: add DE2 CCU related device tree nodes
Date: Sat, 17 Mar 2018 01:53:52 +0800	[thread overview]
Message-ID: <20180316175354.21437-6-icenowy@aosc.io> (raw)
In-Reply-To: <20180316175354.21437-1-icenowy@aosc.io>

As we have all necessary parts to enable the DE2 CCU on the Allwinner
A64 SoC, add the needed device tree nodes, including the SRAM controller
node, SRAM C node, DE2 bus node and DE2 CCU node.
