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'

---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.

bool "Allow child devices for PMICs in SPL"

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).

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.

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:
|
