Subject: [PATCH 1/2] arm64: dts: Update cache properties for socionext
Date: Mon, 23 Oct 2023 11:12:20 +0900	[thread overview]
Message-ID: <20231023021221.2884828-2-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <20231023021221.2884828-1-hayashi.kunihiko@socionext.com>

From: Pierre Gondois <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.
