   5         This config enables the driver-model PMIC support.
   6         UCLASS_PMIC - designed to provide an I/O interface for PMIC devices.
   7         For the multi-function PMIC devices, this can be used as parent I/O
   8         device for each IC's interface. Then, each children uses its parent
   9         for read/write. For detailed description, please refer to the files:

  16         default y
  17         ---help---
  18         This allows PMICs to support child devices (such as regulators) in
  19         SPL. This adds quite a bit of code so if you are not using this
  20         feature you can turn it off. Most likely you should turn it on for
  21         U-Boot proper.

  23 config SPL_PMIC_CHILDREN
  24         bool "Allow child devices for PMICs in SPL"
  25         depends on DM_PMIC
  26         default y
  27         ---help---
  28         This allows PMICs to support child devices (such as regulators) in
  29         SPL. This adds quite a bit of code so if you are not using this
  30         feature you can turn it off. In this case you may need a 'back door'
  31         to call your regulator code (e.g. see rk8xx.c for direct functions
  32         for use in SPL).
