   4 Subject: [PATCH 232/304] BCM270X_DT: Don't generate "linux,phandle" props
   5
   6 The EPAPR standard says to use "phandle" properties to store phandles,
   7 rather than the deprecated "linux,phandle" version. By default, dtc
   8 generates both, but adding "-H epapr" causes it to only generate
   9 "phandle"s, saving some space and clutter.
