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 rk8xx.c for direct functions
for use in SPL).

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)
