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

This allows PMICs to support child devices (such as regulators) in

SPL. This adds quite a bit of code so if you are not using this

to call your regulator code (e.g. see rk8xx.c for direct functions

for use in SPL).
