| 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() |
