depends on DM
|

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'

depends on DM_PMIC
|

---help---
|
|
This config enables implementation of driver-model pmic uclass features
|
|
for PMIC MAX77686. The driver implements read/write operations.

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)
