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? -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
