Subject: [PATCH 1/3] arm64: tegra: Add unit-address for CBB on Tegra194
Date: Fri, 26 Jul 2019 12:16:16 +0200 [thread overview]
Message-ID: <20190726101618.26896-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
The control back-bone (CBB) starts at physical address 0, so give it a
unit-address to comply with standard naming practices checked for by the
device tree compiler.
Signed-off-by: Thierry Reding <treding@nvidia.com>
