2 bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
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...
9 When enabling this, please read the description, found in the files:
10 - 'include/power/pmic.h'
11 - 'include/power/regulator.h'
