Subject: [PATCH v9 11/17] ARM: tegra: Add interconnect properties to Tegra20 device-tree
Date: Mon, 16 Nov 2020 00:29:16 +0300 [thread overview]
Message-ID: <20201115212922.4390-12-digetx@gmail.com> (raw)
In-Reply-To: <20201115212922.4390-1-digetx@gmail.com>
Add interconnect properties to the Memory Controller, External Memory
Controller and the Display Controller nodes in order to describe hardware
interconnection.
