Subject: [PATCH v8 23/26] ARM: tegra: Add nvidia,memory-controller phandle to Tegra20 EMC device-tree
Date:   Wed, 11 Nov 2020 04:14:53 +0300

Precedence: bulk

Add nvidia,memory-controller to the Tegra20 External Memory Controller
node. This allows to perform a direct lookup of the Memory Controller
instead of walking up the whole tree. This puts Tegra20 device-tree on
par with Tegra30+.
