config DM_REGULATOR
bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
depends on DM
---help---
This config enables the driver model regulator support.
UCLASS_REGULATOR - designed to provide a common API for basic regulator's
functions, like get/set Voltage or Current value, enable state, etc...
Note:
When enabling this, please read the description, found in the files:
- 'include/power/pmic.h'
- 'include/power/regulator.h'
- 'drivers/power/pmic/pmic-uclass.c'
- 'drivers/power/pmic/regulator-uclass.c'
It's important to call the device_bind() with the proper node offset,
when binding the regulator devices. The pmic_bind_childs() can be used
for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_node()
otherwise. Detailed information can be found in the header file.
config DM_REGULATOR_MAX77686
bool "Enable Driver Model for REGULATOR MAX77686"
depends on DM_REGULATOR && DM_PMIC_MAX77686
---help---
This config enables implementation of driver-model regulator uclass
features for REGULATOR MAX77686. The driver implements get/set api for:
value, enable and mode.
config DM_REGULATOR_FIXED
bool "Enable Driver Model for REGULATOR Fixed value"
depends on DM_REGULATOR
---help---
This config enables implementation of driver-model regulator uclass
features for fixed value regulators. The driver implements get/set api
for enable and get only for voltage value.
config DM_REGULATOR_SANDBOX
bool "Enable Driver Model for Sandbox PMIC regulator"
depends on DM_REGULATOR && DM_PMIC_SANDBOX
---help---
Enable the regulator driver for emulated Sandbox PMIC.
The emulated PMIC device depends on two drivers:
- sandbox PMIC I/O driver - implements dm pmic operations
- sandbox PMIC regulator driver - implements dm regulator operations
- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
The regulator driver provides uclass operations for sandbox PMIC's
regulators. The driver implements get/set api for: voltage, current,
operation mode and enable state.
The driver supports LDO and BUCK regulators.
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)
A detailed information can be found in header: '<power/sandbox_pmic.h>'
