config DM_PMIC
bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)"
depends on DM
---help---
This config enables the driver-model PMIC support.
UCLASS_PMIC - designed to provide an I/O interface for PMIC devices.
For the multi-function PMIC devices, this can be used as parent I/O
device for each IC's interface. Then, each children uses its parent
for read/write. For detailed description, please refer to the files:
- 'drivers/power/pmic/pmic-uclass.c'
- 'include/power/pmic.h'
config PMIC_CHILDREN
bool "Allow child devices for PMICs"
depends on DM_PMIC
default y
---help---
This allows PMICs to support child devices (such as regulators) in
SPL. This adds quite a bit of code so if you are not using this
feature you can turn it off. Most likely you should turn it on for
U-Boot proper.
config SPL_PMIC_CHILDREN
bool "Allow child devices for PMICs in SPL"
depends on DM_PMIC
default y
---help---
This allows PMICs to support child devices (such as regulators) in
SPL. This adds quite a bit of code so if you are not using this
feature you can turn it off. In this case you may need a 'back door'
to call your regulator code (e.g. see rk808.c for direct functions
for use in SPL).
config PMIC_ACT8846
bool "Enable support for the active-semi 8846 PMIC"
depends on DM_PMIC && DM_I2C
---help---
This PMIC includes 4 DC/DC step-down buck regulators and 8 low-dropout
regulators (LDOs). It also provides some GPIO, reset and battery
functions. It uses an I2C interface and is designed for use with
tablets and smartphones.
config DM_PMIC_PFUZE100
bool "Enable Driver Model for PMIC PFUZE100"
depends on DM_PMIC
---help---
This config enables implementation of driver-model pmic uclass features
for PMIC PFUZE100. The driver implements read/write operations.
config DM_PMIC_MAX77686
bool "Enable Driver Model for PMIC MAX77686"
depends on DM_PMIC
---help---
This config enables implementation of driver-model pmic uclass features
for PMIC MAX77686. The driver implements read/write operations.
config PMIC_RK808
bool "Enable support for Rockchip PMIC RK808"
depends on DM_PMIC
---help---
The Rockchip RK808 PMIC provides four buck DC-DC convertors, 8 LDOs,
an RTC and two low Rds (resistance (drain to source)) switches. It is
accessed via an I2C interface. The device is used with Rockchip SoCs.
This driver implements register read/write operations.
config PMIC_S2MPS11
bool "Enable Driver Model for PMIC Samsung S2MPS11"
depends on DM_PMIC
---help---
The Samsung S2MPS11 PMIC provides:
- 38 adjustable LDO regulators
- 9 High-Efficiency Buck Converters
- 1 BuckBoost Converter
- RTC with two alarms
- Backup battery charger
- I2C Configuration Interface
This driver provides access to I/O interface only.
Binding info: doc/device-tree-bindings/pmic/s2mps11.txt
config DM_PMIC_SANDBOX
bool "Enable Driver Model for emulated Sandbox PMIC "
depends on DM_PMIC
---help---
Enable the driver for Sandbox PMIC emulation. The emulated PMIC device
depends on two drivers:
- sandbox PMIC I/O driver - implements dm pmic operations
- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
A detailed information can be found in header: '<power/sandbox_pmic.h>'
The Sandbox PMIC info:
* I/O interface:
- I2C chip address: 0x40
- first register address: 0x0
- register count: 0x10
* Adjustable outputs:
- 2x LDO
- 2x BUCK
- Each, with a different operating conditions (header).
* Reset values:
- set by i2c emul driver's probe() (defaults in header)

config PMIC_S5M8767
bool "Enable Driver Model for the Samsung S5M8767 PMIC"
depends on DM_PMIC
---help---
The S5M8767 PMIC provides a large array of LDOs and BUCKs for use
as a SoC power controller. It also provides 32KHz clock outputs. This
driver provides basic register access and sets up the attached
regulators if regulator support is enabled.
config PMIC_TPS65090
bool "Enable driver for Texas Instruments TPS65090 PMIC"
depends on DM_PMIC
---help---
The TPS65090 is a PMIC containing several LDOs, DC to DC convertors,
FETs and a battery charger. This driver provides register access
only, and you can enable the regulator/charger drivers separately if
required.
