The node names for devices using the pwm-leds driver follow a certain

I like the consistency this brings. My only feedback is that in the other
examples I found (common.yaml and leds-gpio.yaml), the children count off
from 0 (e.g. led-0) instead of 1 as your series appears to.
That's not a huge deal; it simply seems more consistent to count from the
first index allowed by the regex (0). The patch is still fine, and so:

You're right. And that's also the same in leds-lp50xx.yaml and … well I did
not look close enough, maybe the numbering scheme on the PCB on my desk
confused me.
Okay, we are already talking about starting index. What about the parent
node's "led-controller" then in case there are more than one? IIRC Rob
acknowledged starting from 1 like "led-controller-1", "led-controller-2" and
so on.

Thanks.
I'm not sure how many more iterations of this series we will need, at least
one for the binding license acks I guess, so I could also adapt the child node
indexes in schema and actual dts files in v8 or so.

If you can tie the numbering to the PCB, then do that.

No, I'd assume we start at 0.

Okay, so I need Rob's ack here, I guess... and rest of the series is
not really for my tree.

I think so, too.
I saw you applied patch number 1, all the other patches are DT and from my
side those can wait for the Acks required and maybe I change the indexes again
and I'm fine resending all that after the 5.10 merge window.
Thanks for applying the non-DT patches for leds subsystem, the rest will be
sorted out without hurry.

This patch is not for your tree either. ;)

Ah, right. Usually we have one patch series for one maintainer...
