Subject: [PATCH v5 2/6] ARM: dts: sun8i: v3s: Add mbus node to represent the interconnect
Date: Fri, 26 Aug 2022 20:27:59 +0200 [thread overview]
Message-ID: <20220826182803.604563-3-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20220826182803.604563-1-paul.kocialkowski@bootlin.com>
The V3s uses the mbus interconnect to provide DRAM access for a
number of blocks. The SoC can only map 2 GiB of DRAM, which is
reflected in the dma-ranges property.
