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 DM_REGULATOR_MAX77686
20	bool "Enable Driver Model for REGULATOR MAX77686"
21	depends on DM_REGULATOR && DM_PMIC_MAX77686
22	---help---
23	This config enables implementation of driver-model regulator uclass
24	features for REGULATOR MAX77686. The driver implements get/set api for:
25	value, enable and mode.
26
27config DM_REGULATOR_FIXED
28	bool "Enable Driver Model for REGULATOR Fixed value"
29	depends on DM_REGULATOR
30	---help---
31	This config enables implementation of driver-model regulator uclass
32	features for fixed value regulators. The driver implements get/set api
33	for enable and get only for voltage value.
34
35config DM_REGULATOR_SANDBOX
36	bool "Enable Driver Model for Sandbox PMIC regulator"
37	depends on DM_REGULATOR && DM_PMIC_SANDBOX
38	---help---
39	Enable the regulator driver for emulated Sandbox PMIC.
40	The emulated PMIC device depends on two drivers:
41	- sandbox PMIC I/O driver - implements dm pmic operations
42	- sandbox PMIC regulator driver - implements dm regulator operations
43	- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
44
45	The regulator driver provides uclass operations for sandbox PMIC's
46	regulators. The driver implements get/set api for: voltage, current,
47	operation mode and enable state.
48	The driver supports LDO and BUCK regulators.
49
50	The Sandbox PMIC info:
51	* I/O interface:
52	  - I2C chip address:       0x40
53	  - first register address: 0x0
54	  - register count:         0x10
55	* Adjustable outputs:
56	  - 2x LDO
57	  - 2x BUCK
58	  - Each, with a different operating conditions (header).
59	* Reset values:
60	  - set by i2c emul driver's probe() (defaults in header)
61
62	A detailed information can be found in header: '<power/sandbox_pmic.h>'
