   4 Subject: [PATCH] arm64: dts: Update cache properties for broadcom
   5
   6 The DeviceTree Specification v0.3 specifies that the cache node
   7 'compatible' and 'cache-level' properties are 'required'. Cf.
   8 s3.8 Multi-level and Shared Cache Nodes
   9 The 'cache-unified' property should be present if one of the
  10 properties for unified cache is present ('cache-size', ...).
  11
  12 Update the Device Trees accordingly.
