config DM_REGULATOR
	bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
	depends on DM
	---help---
	This config enables the driver model regulator support.
	UCLASS_REGULATOR - designed to provide a common API for basic regulator's
	functions, like get/set Voltage or Current value, enable state, etc...
	Note:
	When enabling this, please read the description, found in the files:
	- 'include/power/pmic.h'
	- 'include/power/regulator.h'
	- 'drivers/power/pmic/pmic-uclass.c'
	- 'drivers/power/pmic/regulator-uclass.c'
	It's important to call the device_bind() with the proper node offset,
	when binding the regulator devices. The pmic_bind_childs() can be used
	for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_dev()
	otherwise. Detailed information can be found in the header file.
