Subject: [PATCH v2 06/23] arm64: dts: Update cache properties for broadcom
Date: Mon,  7 Nov 2022 16:56:59 +0100	[thread overview]
Message-ID: <20221107155825.1644604-7-pierre.gondois@arm.com> (raw)
In-Reply-To: <20221107155825.1644604-1-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.
