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.
18
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
24	code space can be saved by accessing the PMIC registers directly.
25	Enable this option if you need regulators in SPL and can cope with
26	the extra code size.
27
28config REGULATOR_ACT8846
29	bool "Enable driver for ACT8846 regulator"
30	depends on DM_REGULATOR && PMIC_ACT8846
31	---help---
32	Enable support for the regulator functions of the ACT8846 PMIC. The
33	driver implements get/set api for the various BUCKS and LDOS supported
34	by the PMIC device. This driver is controlled by a device tree node
35	which includes voltage limits.
36
37config DM_REGULATOR_PFUZE100
38	bool "Enable Driver Model for REGULATOR PFUZE100"
39	depends on DM_REGULATOR && DM_PMIC_PFUZE100
40	---help---
41	This config enables implementation of driver-model regulator uclass
42	features for REGULATOR PFUZE100. The driver implements get/set api for:
43	value, enable and mode.
44
45config DM_REGULATOR_MAX77686
46	bool "Enable Driver Model for REGULATOR MAX77686"
47	depends on DM_REGULATOR && DM_PMIC_MAX77686
48	---help---
49	This config enables implementation of driver-model regulator uclass
50	features for REGULATOR MAX77686. The driver implements get/set api for:
51	value, enable and mode.
52
53config DM_REGULATOR_FIXED
54	bool "Enable Driver Model for REGULATOR Fixed value"
55	depends on DM_REGULATOR
56	---help---
57	This config enables implementation of driver-model regulator uclass
58	features for fixed value regulators. The driver implements get/set api
59	for enable and get only for voltage value.
60
61config REGULATOR_RK808
62	bool "Enable driver for RK808 regulators"
63	depends on DM_REGULATOR && PMIC_RK808
64	---help---
65	Enable support for the regulator functions of the RK808 PMIC. The
66	driver implements get/set api for the various BUCKS and LDOs supported
67	by the PMIC device. This driver is controlled by a device tree node
68	which includes voltage limits.
69
70config REGULATOR_S5M8767
71	bool "Enable support for S5M8767 regulator"
72	depends on DM_REGULATOR && PMIC_S5M8767
73	---help---
74	This enables the regulator features of the S5M8767, allowing voltages
75	to be set, etc. The driver is not fully complete but supports most
76	common requirements, including all LDOs and BUCKs. This allows many
77	supplies to be set automatically using the device tree values.
78
79config DM_REGULATOR_SANDBOX
80	bool "Enable Driver Model for Sandbox PMIC regulator"
81	depends on DM_REGULATOR && DM_PMIC_SANDBOX
82	---help---
83	Enable the regulator driver for emulated Sandbox PMIC.
84	The emulated PMIC device depends on two drivers:
85	- sandbox PMIC I/O driver - implements dm pmic operations
86	- sandbox PMIC regulator driver - implements dm regulator operations
87	- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
88
89	The regulator driver provides uclass operations for sandbox PMIC's
90	regulators. The driver implements get/set api for: voltage, current,
91	operation mode and enable state.
92	The driver supports LDO and BUCK regulators.
93
94	The Sandbox PMIC info:
95	* I/O interface:
96	  - I2C chip address:       0x40
97	  - first register address: 0x0
98	  - register count:         0x10
99	* Adjustable outputs:
100	  - 2x LDO
101	  - 2x BUCK
102	  - Each, with a different operating conditions (header).
103	* Reset values:
104	  - set by i2c emul driver's probe() (defaults in header)
105
106	A detailed information can be found in header: '<power/sandbox_pmic.h>'
107	Binding info: 'doc/device-tree-bindings/pmic/max77686.txt'
108
109config REGULATOR_TPS65090
110	bool "Enable driver for TPS65090 PMIC regulators"
111	depends on PMIC_TPS65090
112	---help---
113	The TPS65090 provides several FETs (Field-effect Transistors,
114	effectively switches) which are supported by this driver as
115	regulators, one for each FET. The standard regulator interface is
116	supported, but it is only possible to turn the regulators on or off.
117	There is no voltage/current control.
