2 bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
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...
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.
19 config SPL_DM_REGULATOR
20 bool "Enable regulators for SPL"
21 depends on DM_REGULATOR
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
28 config REGULATOR_ACT8846
29 bool "Enable driver for ACT8846 regulator"
30 depends on DM_REGULATOR && PMIC_ACT8846
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.
37 config DM_REGULATOR_PFUZE100
38 bool "Enable Driver Model for REGULATOR PFUZE100"
39 depends on DM_REGULATOR && DM_PMIC_PFUZE100
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.
46 bool "Enable driver for PWM regulators"
47 depends on DM_REGULATOR
49 Enable support for the PWM regulator functions which voltage are
50 controlled by PWM duty ratio. Some of Rockchip board using this kind
51 of regulator. The driver implements get/set api for the various BUCKS.
52 This driver is controlled by a device tree node
53 which includes voltage limits.
55 config DM_REGULATOR_MAX77686
56 bool "Enable Driver Model for REGULATOR MAX77686"
57 depends on DM_REGULATOR && DM_PMIC_MAX77686
59 This config enables implementation of driver-model regulator uclass
60 features for REGULATOR MAX77686. The driver implements get/set api for:
61 value, enable and mode.
63 config DM_REGULATOR_FIXED
64 bool "Enable Driver Model for REGULATOR Fixed value"
65 depends on DM_REGULATOR
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.
71 config REGULATOR_RK808
72 bool "Enable driver for RK808 regulators"
73 depends on DM_REGULATOR && PMIC_RK808
75 Enable support for the regulator functions of the RK808 PMIC. The
76 driver implements get/set api for the various BUCKS and LDOs supported
77 by the PMIC device. This driver is controlled by a device tree node
78 which includes voltage limits.
80 config REGULATOR_S5M8767
81 bool "Enable support for S5M8767 regulator"
82 depends on DM_REGULATOR && PMIC_S5M8767
84 This enables the regulator features of the S5M8767, allowing voltages
85 to be set, etc. The driver is not fully complete but supports most
86 common requirements, including all LDOs and BUCKs. This allows many
87 supplies to be set automatically using the device tree values.
89 config DM_REGULATOR_SANDBOX
90 bool "Enable Driver Model for Sandbox PMIC regulator"
91 depends on DM_REGULATOR && DM_PMIC_SANDBOX
93 Enable the regulator driver for emulated Sandbox PMIC.
94 The emulated PMIC device depends on two drivers:
95 - sandbox PMIC I/O driver - implements dm pmic operations
96 - sandbox PMIC regulator driver - implements dm regulator operations
97 - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
99 The regulator driver provides uclass operations for sandbox PMIC's
100 regulators. The driver implements get/set api for: voltage, current,
101 operation mode and enable state.
102 The driver supports LDO and BUCK regulators.
104 The Sandbox PMIC info:
106 - I2C chip address: 0x40
107 - first register address: 0x0
108 - register count: 0x10
109 * Adjustable outputs:
112 - Each, with a different operating conditions (header).
114 - set by i2c emul driver's probe() (defaults in header)
116 A detailed information can be found in header: '<power/sandbox_pmic.h>'

119 config REGULATOR_TPS65090
120 bool "Enable driver for TPS65090 PMIC regulators"
121 depends on PMIC_TPS65090
123 The TPS65090 provides several FETs (Field-effect Transistors,
124 effectively switches) which are supported by this driver as
125 regulators, one for each FET. The standard regulator interface is
126 supported, but it is only possible to turn the regulators on or off.
127 There is no voltage/current control.
