The reason I noticed this is that it appears to differ from led nodes for other Renesas ARM SoCs.
I was looking at the Koelsch's DT as an example (and Gose's DT also had labels).
I'm not opposed to using the label property if there is some value to it. But I would prefer to use it consistently. And I'd prefer not to add it to all the other SoCs unless there is a reason to.
Looks like the driver can infer the LED names from the device node names. I'll recast.
