Subject: [PATCH v10 14/19] ARM: tegra: Add interconnect properties to Tegra30 device-tree
Date: Mon, 23 Nov 2020 03:27:18 +0300	[thread overview]
Message-ID: <20201123002723.28463-15-digetx@gmail.com> (raw)
In-Reply-To: <20201123002723.28463-1-digetx@gmail.com>

Add interconnect properties to the Memory Controller, External Memory
Controller and the Display Controller nodes in order to describe hardware
interconnection.
