> Subject: [PATCH 07/20] arm64: dts: Update cache properties for freescale
>
> 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.
