ARM: dts: imx28-apx4devkit: Convert to use label references
Browse files Browse the repository at this point in the history 
This board file 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 orer to make it
easier to maintain.
