Simon Glass d308c0136d dm: power: Add support for the S5M8767 PMIC
This PMIC is used with SoCs which need a combination of BUCKs and LDOs. The
driver supports probing and basic register access. It supports the standard
device tree binding and supports driver model. A regulator driver can be
provided also.

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 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 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.
