I agree that using "clock-xin24m" makes more sense in general, but the
trouble is that we can't rename the already existing instances of
"xin24m",
because that has become part of the ABI. Thus, I'm not sure that
breaking
away from the legacy brings benefits in this particular case.
In the regulator case, we have _new_ boards using the new _node_-names
but I don't see any renaming of old boards and also don't think we
should.
But that still does not keep us from using the nicer naming convention
in
new boards ;-) .
Same with xin24m. We're talking only about the node-name here. The
phandle stays the same and also the actual clock name stays the same
and
really only the actual node name you need to look for in
/proc/device-tree
changes ;-) .
So I don't see the need to go about changing all the old socs, but new
additions should use improved naming conventions.
xin24m: clock-xin24m {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <24000000>;
clock-output-names = "xin24m";
};
Makes sense. Though, updating the dtsi files for older SoCs to follow
the new rules, if possible, still remains an itch to me. :)
