1config DM_REGULATOR
2	bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
3	depends on DM
4	---help---
5	This config enables the driver model regulator support.
6	UCLASS_REGULATOR - designed to provide a common API for basic regulator's
7	functions, like get/set Voltage or Current value, enable state, etc...
8	Note:
9	When enabling this, please read the description, found in the files:
10	- 'include/power/pmic.h'
11	- 'include/power/regulator.h'
12	- 'drivers/power/pmic/pmic-uclass.c'
13	- 'drivers/power/pmic/regulator-uclass.c'
14	It's important to call the device_bind() with the proper node offset,
15	when binding the regulator devices. The pmic_bind_childs() can be used
16	for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_dev()
17	otherwise. Detailed information can be found in the header file.
