Thanks for confirming.

I noticed this using make dtbs W=1

I have fixed this up locally and applied your patch. The result is:


From: Kieran Bingham <kieran.bingham+renesas@xxxxxxxxxxxxxxxx>
Subject: [PATCH] arm64: dts: renesas: r8a77995: add VSP instances

The r8a77995 has a VSPBS to support image processing such as blending of
two input images, and has two VSPDs to handle display pipelines with a
DU.
