According to Devicetree Specification v0.2 document: "The name of a node should be somewhat generic, reflecting the function of the device and not its precise programming model." Also, the reg property needs to have a corresponding unit address. It would better to rewrite this as: mc34708: pmic@41 { reg = <0x41> };

I've blindly followed the current (wrong) code. I'm now waiting for comments from Simon and will fix this in v3. Thanks for review.
