Hi.


Decumentation/devicetree/bindings/opp/opp.txt
takes examples like this:

        opp at 1000000000 {
                opp-hz = /bits/ 64 <1000000000>;
                opp-microvolt = <970000 975000 985000>;
                opp-microamp = <70000>;
                clock-latency-ns = <300000>;
                opp-suspend;
        };

quoted

If we follow this notation and the device-tree is built with W=1,
DTC warns like follows:

Warning (unit_address_vs_reg): Node /opp_table0/opp at 1000000000 has a
unit name, but no reg property

Is there a recommended notation to avoid it?

Maybe, simply omit the "@" ?

I think just s/@/-/ should be fine, e.g. call the above opp-1000000000.

That's fine with me. I can send a patch to fix all existing users if we all
agree for it.

Any progress on this?

Did we reach on agreement with s/@/-/  ?

We can follow this as no one else objected. I will send a patch for existing
entries and you can do it for the newer ones.
