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_dev()
otherwise. Detailed information can be found in the header file.
