Please, don't use simple-bus like that. The components below this node
depend on it. It is _NOT_ a simple bus. Make the ti,control-syscon
driver probe it's children.
Hi Mark,
Actually ti,control-syscon driver does not exist, so I can remove it,
and simple-bus is needed for child creation.
This still shows up as a syscon node, with a reg property, and syscon is
not an extension of simple-bus.
There are properties in the parent node that children depend on, and
that makes me wary of describing it as a simple bus. I'd expect to be
able to move child nodes out of a simple-bus if ranges provided an
idmap, and I can't do that here.
Hi Mark,
Not sure if I am understanding here, can you please add more info.
Hi Mark,
From Documentation/devicetree/bindings.. , I could get below info about simple-bus
- "simple-bus" compatible value (to ensure creation of the children)
compatible = "simple-bus";
Thanks,
Mark.
