Subject: parent/child hierarchy for regulator
Hi lists,
Any good ways at code/dts to show parent/child hierarchy for regulator?
The related regulators at my platforms like below:
PMIC (SWB 5v) --> Switch Chip (GPIO Regulator) --> USB VBUS
PMIC has one 5V regulator (eg, swbst at pfuse), and it is the input
for USB power switch chip, and there are two gpios at this switch
chip to control if 5V is output or not, we register these two gpios as
fixed regulators, currently, if regulator swbst is disabled, the
gpio regulator has no way to know, and cause the vbus voltage is wrong.
Thanks in advance.
