[PATCH v2 12/23] arm64: dts: Update cache properties for mediatek

From: Pierre Gondois <pierre.gondois@arm.com>
Date: 2022-11-07 16:24:42
Also in: linux-amlogic, linux-arm-msm, linux-mediatek, linux-renesas-soc, linux-samsung-soc, linux-tegra, lkml
Subsystem: arm/mediatek soc support, the rest · Maintainers: Matthias Brugger, AngeloGioacchino Del Regno, Linus Torvalds

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.
