PATCH 1/1 ARM: dts: phycore-imx6: set buck regulator modes explicitly
This patch sets initial buck regulator modes explicitly to a state this hardware needs. So a wrong initial mode set by bootloader or pmic itself does not interfere anymore.

According to Documentation/devicetree/bindings/regulator/twl-regulator.txt:
"- regulator-initial-mode: initial operating mode. The set of possible operating
modes depends on the capabilities of every hardware so each device binding documentation explains which values the regulator supports."
However, I haven't found the explanation of this property for the da9062-regulator.
Could you please add it into Documentation/devicetree/bindings/mfd/da9062.txt, so that we we know what the value 2 means here?

Thanks for pointing that out, I'll send a patchset with all changes.
