The above hx4700 patch yields the following warnings:

_regulator_get: gpio-vbus supply vbus_draw not found, using dummy regulator
_regulator_get: pda-power supply ac_draw not found, using dummy regulator

I suggest the following lines instead:

	REGULATOR_SUPPLY("vbus_draw", "gpio-vbus"),
	REGULATOR_SUPPLY("ac_draw", "pda-power"),
