Thanks for your patch!

To avoid regressions (/sys/devices/soc0/ disappearing), enabling sysc
is a dependency for "[PATCH 05/16] soc: renesas: sysc: Move RZ/G3S
SoC detection on SYSC driver", so I think it makes sense to change
its status to "okay" in r9a08g045.dtsi instead, and spin that off into
its own patch.  I am not super-worried, so doing the driver and DTS
changes in separate patches should be fine, as long as they meet each
other in next or upstream.

The rest LGTM.

Gr{oetje,eeting}s,

Good point! I'll add the dtsi changes into "[PATCH 05/16] soc: renesas:
sysc: Move RZ/G3S SoC detection on SYSC driver".

Thank you,
