Hi,

sorry for the mess, it was asked to give an user of the LED feature for
qca8k so I was a bit confused on where to include it and at the end I
decided to put it in this series.

What was the correct way? 2 different series and reference the DT one in
the net-next? (or not targetting net-next at all?)
