SubjectRFC power domain vs generic supply regulator
Hi all

I'm trying to understand how to deal with devices that do not provide
a supply handle connection using the device tree, or if there is a
generic way
to connect to a regulator. The pinctrl has a generic binding inside
dd.c that allow to mux pinout during probing or it allows to define a
power domain,
According to the code I read the power domain can be only connected to
the SoC power domain but in general a generic power domain can be
connected
to any source aka a regulator. For example and spi-nor can be powered
but a gpio regulator or any kind of supply connection and bunch of
devices
can just need a supply if they are probed or binded runtime. Can
someone give me feedback on this topic?

Michael
