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.
