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_node()
17	otherwise. Detailed information can be found in the header file.

19config REGULATOR_ACT8846
20	bool "Enable driver for ACT8846 regulator"
21	depends on DM_REGULATOR && PMIC_ACT8846
22	---help---
23	Enable support for the regulator functions of the ACT8846 PMIC. The
24	driver implements get/set api for the various BUCKS and LDOS supported
25	by the PMIC device. This driver is controlled by a device tree node
26	which includes voltage limits.
27
28config DM_REGULATOR_PFUZE100
29	bool "Enable Driver Model for REGULATOR PFUZE100"
30	depends on DM_REGULATOR && DM_PMIC_PFUZE100
31	---help---
32	This config enables implementation of driver-model regulator uclass
33	features for REGULATOR PFUZE100. The driver implements get/set api for:
34	value, enable and mode.
35
36config DM_REGULATOR_MAX77686
37	bool "Enable Driver Model for REGULATOR MAX77686"
38	depends on DM_REGULATOR && DM_PMIC_MAX77686
39	---help---
40	This config enables implementation of driver-model regulator uclass
41	features for REGULATOR MAX77686. The driver implements get/set api for:
42	value, enable and mode.
43
44config DM_REGULATOR_FIXED
45	bool "Enable Driver Model for REGULATOR Fixed value"
46	depends on DM_REGULATOR
47	---help---
48	This config enables implementation of driver-model regulator uclass
49	features for fixed value regulators. The driver implements get/set api
50	for enable and get only for voltage value.
51
52config REGULATOR_S5M8767
53	bool "Enable support for S5M8767 regulator"
54	depends on DM_REGULATOR && PMIC_S5M8767
55	---help---
56	This enables the regulator features of the S5M8767, allowing voltages
57	to be set, etc. The driver is not fully complete but supports most
58	common requirements, including all LDOs and BUCKs. This allows many
59	supplies to be set automatically using the device tree values.
60
61config DM_REGULATOR_SANDBOX
62	bool "Enable Driver Model for Sandbox PMIC regulator"
63	depends on DM_REGULATOR && DM_PMIC_SANDBOX
64	---help---
65	Enable the regulator driver for emulated Sandbox PMIC.
66	The emulated PMIC device depends on two drivers:
67	- sandbox PMIC I/O driver - implements dm pmic operations
68	- sandbox PMIC regulator driver - implements dm regulator operations
69	- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
70
71	The regulator driver provides uclass operations for sandbox PMIC's
72	regulators. The driver implements get/set api for: voltage, current,
73	operation mode and enable state.
74	The driver supports LDO and BUCK regulators.
75
76	The Sandbox PMIC info:
77	* I/O interface:
78	  - I2C chip address:       0x40
79	  - first register address: 0x0
80	  - register count:         0x10
81	* Adjustable outputs:
82	  - 2x LDO
83	  - 2x BUCK
84	  - Each, with a different operating conditions (header).
85	* Reset values:
86	  - set by i2c emul driver's probe() (defaults in header)
87
88	A detailed information can be found in header: '<power/sandbox_pmic.h>'
89	Binding info: 'doc/device-tree-bindings/pmic/max77686.txt'

91config REGULATOR_TPS65090
92	bool "Enable driver for TPS65090 PMIC regulators"
93	depends on PMIC_TPS65090
94	---help---
95	The TPS65090 provides several FETs (Field-effect Transistors,
96	effectively switches) which are supported by this driver as
97	regulators, one for each FET. The standard regulator interface is
98	supported, but it is only possible to turn the regulators on or off.
99	There is no voltage/current control.
