This should not be needed. All 6282 have the thermal sensor, so the
kirkwood-6282.dtsi will contain this. For 3.9 we submitted the DT
change too late, so it did not make it in, but for 3.10 it should be
there.

As Jason said, you can use a fixed regulator, in DT. Something like:

        regulators {
                compatible = "simple-bus";
                #address-cells = <1>;
                #size-cells = <0>;

                usb_power: regulator at 1 {
                        compatible = "regulator-fixed";
                        reg = <1>;
                        regulator-name = "USB Power";
                        regulator-min-microvolt = <5000000>;
                        regulator-max-microvolt = <5000000>;
                        enable-active-high;
                        regulator-always-on;
                        regulator-boot-on;
                        gpio = <&gpio0 14 0>;
                };
        };

Is the mdelay() really required?
