Subject: [PATCH v2 3/3] ARM: dts: mvebu: add sdram controller node to Armada-38x
Date: Thu, 11 Jan 2018 14:59:03 +1300 [thread overview]
Message-ID: <20180111015903.11322-4-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20180111015903.11322-1-chris.packham@alliedtelesis.co.nz>
The Armada-38x uses an SDRAM controller that is compatible with the
Armada-XP. The key difference is the width of the bus (XP is 64/32, 38x
is 32/16). The SDRAM controller registers are the same between the two
SoCs.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>

Changes in v2:
- Add label to sdram-controller node
