   4         ---help---
   5         This config enables the driver model regulator support.
   6         UCLASS_REGULATOR - designed to provide a common API for basic regulator's
   7         functions, like get/set Voltage or Current value, enable state, etc...
   8         Note:
   9         When enabling this, please read the description, found in the files:
  10         - 'include/power/pmic.h'
  11         - 'include/power/regulator.h'
  12         - 'drivers/power/pmic/pmic-uclass.c'
  13         - 'drivers/power/pmic/regulator-uclass.c'
  14         It's important to call the device_bind() with the proper node offset,
  15         when binding the regulator devices. The pmic_bind_childs() can be used
  16         for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_dev()
  17         otherwise. Detailed information can be found in the header file.

  22         ---help---
  23         Regulators are seldom needed in SPL. Even if they are accessed, some
  24         code space can be saved by accessing the PMIC registers directly.
  25         Enable this option if you need regulators in SPL and can cope with
  26         the extra code size.
