ARM: dts: imx28-cfa10036: Convert to use label references
Browse files Browse the repository at this point in the history 
These Crystal fontz board files still use node name and unit
address to reference parts from the imx28.dtsi . This causes
a lot of redundancy. So use label references in order to make
it easier to maintain.
