Subject: [PATCH 6.1 10/10] arm64: tegra: Update cache properties
From: Pierre Gondois <pierre.gondois@....com>
[ Upstream commit 27f1568b1d5fe35014074f92717b250afbe67031 ]
The DeviceTree Specification v0.3 specifies that the cache node
'compatible' and 'cache-level' properties are 'required'. Cf.
s3.8 Multi-level and Shared Cache Nodes
The 'cache-unified' property should be present if one of the
properties for unified cache is present ('cache-size', ...).
Update the Device Trees accordingly.
