[PATCH 11/20] arm64: dts: Update cache properties for mediatek

Mon Oct 31 02:20:25 PDT 2022


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 recently added init_of_cache_level() function checks
these properties. Add them if missing.
