Optional properties:
- Any optional property defined in bindings/regulator/regulator.txt
For twl4030 regulators/LDOs:
 - regulator-initial-mode:
  - 0x08 - Sleep mode, the nominal output voltage is maintained with low power
           consumption with low load current capability.
  - 0x0e - Active mode, the regulator can deliver its nominal output voltage
           with full-load current capability.

Example:

	xyz: regulator@0 {
		compatible = "ti,twl6030-vaux1";
		regulator-min-microvolt  = <1000000>;
		regulator-max-microvolt  = <3000000>;
	};

For twl6030 regulators/LDOs:

 - ti,retain-on-reset: Does not turn off the supplies during warm
                       reset. Could be needed for VMMC, as TWL6030
                       reset sequence for this signal does not comply
                       with the SD specification.
