2 bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)"
5 This config enables the driver-model PMIC support.
6 UCLASS_PMIC - designed to provide an I/O interface for PMIC devices.
7 For the multi-function PMIC devices, this can be used as parent I/O
8 device for each IC's interface. Then, each children uses its parent
9 for read/write. For detailed description, please refer to the files:
10 - 'drivers/power/pmic/pmic-uclass.c'
11 - 'include/power/pmic.h'
14 bool "Allow child devices for PMICs"
18 This allows PMICs to support child devices (such as regulators) in
19 SPL. This adds quite a bit of code so if you are not using this
20 feature you can turn it off. Most likely you should turn it on for
23 config SPL_PMIC_CHILDREN
24 bool "Allow child devices for PMICs in SPL"
28 This allows PMICs to support child devices (such as regulators) in
29 SPL. This adds quite a bit of code so if you are not using this
30 feature you can turn it off. In this case you may need a 'back door'
31 to call your regulator code (e.g. see rk808.c for direct functions
35 bool "Enable support for the active-semi 8846 PMIC"
36 depends on DM_PMIC && DM_I2C
38 This PMIC includes 4 DC/DC step-down buck regulators and 8 low-dropout
39 regulators (LDOs). It also provides some GPIO, reset and battery
40 functions. It uses an I2C interface and is designed for use with
41 tablets and smartphones.
43 config DM_PMIC_PFUZE100
44 bool "Enable Driver Model for PMIC PFUZE100"
47 This config enables implementation of driver-model pmic uclass features
48 for PMIC PFUZE100. The driver implements read/write operations.
50 config DM_PMIC_MAX77686
51 bool "Enable Driver Model for PMIC MAX77686"
54 This config enables implementation of driver-model pmic uclass features
55 for PMIC MAX77686. The driver implements read/write operations.
58 bool "Enable support for Rockchip PMIC RK808"
61 The Rockchip RK808 PMIC provides four buck DC-DC convertors, 8 LDOs,
62 an RTC and two low Rds (resistance (drain to source)) switches. It is
63 accessed via an I2C interface. The device is used with Rockchip SoCs.
64 This driver implements register read/write operations.
67 bool "Enable Driver Model for PMIC Samsung S2MPS11"
70 The Samsung S2MPS11 PMIC provides:
71 - 38 adjustable LDO regulators
72 - 9 High-Efficiency Buck Converters
73 - 1 BuckBoost Converter
75 - Backup battery charger
76 - I2C Configuration Interface
77 This driver provides access to I/O interface only.

80 config DM_PMIC_SANDBOX
81 bool "Enable Driver Model for emulated Sandbox PMIC "
84 Enable the driver for Sandbox PMIC emulation. The emulated PMIC device
85 depends on two drivers:
86 - sandbox PMIC I/O driver - implements dm pmic operations
87 - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
89 A detailed information can be found in header: '<power/sandbox_pmic.h>'
91 The Sandbox PMIC info:
93 - I2C chip address: 0x40
94 - first register address: 0x0
95 - register count: 0x10
99 - Each, with a different operating conditions (header).
101 - set by i2c emul driver's probe() (defaults in header)

106 bool "Enable Driver Model for the Samsung S5M8767 PMIC"
109 The S5M8767 PMIC provides a large array of LDOs and BUCKs for use
110 as a SoC power controller. It also provides 32KHz clock outputs. This
111 driver provides basic register access and sets up the attached
112 regulators if regulator support is enabled.
115 bool "Enable driver for Texas Instruments TPS65090 PMIC"
118 The TPS65090 is a PMIC containing several LDOs, DC to DC convertors,
119 FETs and a battery charger. This driver provides register access
120 only, and you can enable the regulator/charger drivers separately if
