| |
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
