Indeed. Patches for drivers/soc/renesas/ are supposed to go upstream
through the renesas-devel and soc trees. This patch has no dependencies
on anything else in the series (or vice versa), so there is no reason
to deviate from that, and possibly cause conflicts later.

BTW, I will convert to of_node_to_fwnode() while applying.

Thanks!
