Thanks for your patch!

Oops, one pin too many (29 != 23 + 7).
The checker would have told you:

    Pin 61 is not in bias info list
    WARNING: CPU: 3 PID: 1 at drivers/pinctrl/renesas/pinctrl.c:852

The rest is fine, so

i.e. will queue in renesas-pinctrl-for-v5.20, with the offending
line dropped.

Gr{oetje,eeting}s,
