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 Driver Model for Qualcomm PM8916 PMIC"
61 The PM8916 is a PMIC connected to one (or several) processors
62 with SPMI bus. It has 2 slaves with several peripherals:
65 - Power and Reset buttons
71 Driver binding info: doc/device-tree-bindings/pmic/pm8916.txt
74 bool "Enable support for Rockchip PMIC RK808"
77 The Rockchip RK808 PMIC provides four buck DC-DC convertors, 8 LDOs,
78 an RTC and two low Rds (resistance (drain to source)) switches. It is
79 accessed via an I2C interface. The device is used with Rockchip SoCs.
80 This driver implements register read/write operations.
83 bool "Enable Driver Model for PMIC Samsung S2MPS11"
86 The Samsung S2MPS11 PMIC provides:
87 - 38 adjustable LDO regulators
88 - 9 High-Efficiency Buck Converters
89 - 1 BuckBoost Converter
91 - Backup battery charger
92 - I2C Configuration Interface
93 This driver provides access to I/O interface only.
94 Binding info: doc/device-tree-bindings/pmic/s2mps11.txt
96 config DM_PMIC_SANDBOX
97 bool "Enable Driver Model for emulated Sandbox PMIC "
100 Enable the driver for Sandbox PMIC emulation. The emulated PMIC device
101 depends on two drivers:
102 - sandbox PMIC I/O driver - implements dm pmic operations
103 - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
105 A detailed information can be found in header: '<power/sandbox_pmic.h>'
107 The Sandbox PMIC info:
109 - I2C chip address: 0x40
110 - first register address: 0x0
111 - register count: 0x10
112 * Adjustable outputs:
115 - Each, with a different operating conditions (header).
117 - set by i2c emul driver's probe() (defaults in header)
119 Driver binding info: doc/device-tree-bindings/pmic/sandbox.txt
122 bool "Enable Driver Model for the Samsung S5M8767 PMIC"
125 The S5M8767 PMIC provides a large array of LDOs and BUCKs for use
126 as a SoC power controller. It also provides 32KHz clock outputs. This
127 driver provides basic register access and sets up the attached
128 regulators if regulator support is enabled.
131 bool "Enable driver for Ricoh RN5T567 PMIC"
134 The RN5T567 is a PMIC with 4 step-down DC/DC converters, 5 LDO
135 regulators Real-Time Clock and 4 GPIOs. This driver provides
136 register access only.
139 bool "Enable driver for Texas Instruments TPS65090 PMIC"
142 The TPS65090 is a PMIC containing several LDOs, DC to DC convertors,
143 FETs and a battery charger. This driver provides register access
144 only, and you can enable the regulator/charger drivers separately if
