* Pandora Nub (vsense)

Required SoC Specific Properties:
- compatible: should be one of the following
   - "pandora,pandora-nub":

Optional Properties specific to linux:
- vcc-supply: the vcc supply
- reg: the i2c address (<0x66> or <0x67>)
- gpios: the interrupt gpio and the (shared) reset gpio

Example:
	vsense-left@66 {
		compatible = "pandora,pandora-nub";
		vcc-supply = <&vaux4>;
		reg = <0x66>;
		gpios = <&gpio6 1 GPIO_ACTIVE_LOW>,	/* GPIO_161 */
			<&gpio5 28 GPIO_ACTIVE_LOW>;	/* GPIO_156 */
		interrupt-parent = <&gpio6>;
		interrupts = <1 IRQ_TYPE_EDGE_RISING>;	/* GPIO_161 low-to-high edge */
	};
