You need to also drop the unit address.
That said, looking at the dts it's quite nice to have the address of
these nodes. So perhaps we should fix up the binding and populate reg
instead?

Well, leaving the unit address in the node label was done to
preserve the address information which might be needed later
(for better readibility).
However, fixing up the binding and populating reg property would
make more sense if the driver actually needs it. Looking at the
qcom led driver in its current form, it doesn't seem to require the
same. Please correct me if I am wrong (as I just had a quick look
at the same).
However, if we still want to have the unit addresses and the reg
property for better readibility in the dts, may be we can mark reg
as an optional property in the binding and leave it up to the
driver to use it (with a future update) optionally.
Please let me know your views.

That is correct, the current Linux implementation does not make use of
this information.

Requiring the property only means that the dts is required to have it
specified, not that the driver actually needs to read and use it.
So I'm in favor of amending the DT binding to have the reg specified -
and leaving the Linux driver as is.
