Subject: [PATCH v3 2/2] arm64: dts: Update cache properties for fds
Date:   Wed, 23 Nov 2022 10:01:04 +0100
Message-Id: <20221123090109.74441-3-pierre.gondois@arm.com>

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.
