[PATCH 1/4] arm64: dts: renesas: r9a09g056: Add ICU node
Posted by Prabhakar 6 days ago 
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Add node for the Interrupt Control Unit IP found on the Renesas
RZ/V2N SoC, and modify the pinctrl node as its interrupt parent
is the ICU node.

I will drop the fallback compatible while applying.

i.e. will queue in renesas-devel for v6.20.
