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.

19config SPL_DM_REGULATOR
20	bool "Enable regulators for SPL"
21	depends on DM_REGULATOR
22	---help---
23	Regulators are seldom needed in SPL. Even if they are accessed, some

25	Enable this option if you need regulators in SPL and can cope with
26	the extra code size.

64	bool "Enable Driver Model for REGULATOR Fixed value"
65	depends on DM_REGULATOR
66	---help---
67	This config enables implementation of driver-model regulator uclass
68	features for fixed value regulators. The driver implements get/set api
69	for enable and get only for voltage value.

72	bool "Enable Driver Model for GPIO REGULATOR"
73	depends on DM_REGULATOR
74	---help---
75	This config enables implementation of driver-model regulator uclass
76	features for gpio regulators. The driver implements get/set for
77	voltage value.

80	bool "Enable driver for RK808 regulators"
81	depends on DM_REGULATOR && PMIC_RK808
82	---help---
83	Enable support for the regulator functions of the RK808 PMIC. The

119	  - 2x BUCK
120	  - Each, with a different operating conditions (header).
121	* Reset values:
122	  - set by i2c emul driver's probe() (defaults in header)
