So far the patch worked correctly.

I use [1] for the submissions and seems in 99.9% it works just as expected. Can you compare the difference in the heuristics?

I don't think there is a need to add renesas-soc (or me, FWIW ;-), unless the specific device is used on Renesas platforms. Gr{oetje,eeting}s, Geert
