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:

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.

---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)

---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.

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.
