[PATCH 0/2] arm64: dts: renesas: Enable ISP and IVC on RZ/V2H EVK

[Linus Walleij]

Add the RZ/V2H(P) IVC and Arm Mali-C55 ISP nodes, connect their video
endpoints, and enable both blocks on the RZ/V2H EVK.

After these patches, and enabling the right Linux drivers, we get
this in the console:
mali-c55 16080000.isp: Detected Mali-C55 ISP 9000043.31032022.0

This was done in order to enable booting mainline with mainline
device trees.

Don't blame the LLM, it's me.

I didn't find Daniel's original submission, just noticed this
never made it upstream.

I'll address the comments and send a v2.

Huh; not sure why I never followed up on this. I haven't touched the board in some time, so it must 
have slipped my mind. I can pick it back up and address the comments, including adding the other 
interrupts.

Same for "[PATCH] arm64: dts: renesas: r9a09g057h48-kakip: Enable eth0"?

Ah - yes! I'll revive that since Linus is handling the IVC / ISP ones

Geert commented on the commit message in the original series, that
comment seems to have been ignored.

This gives the impression that Dan's original patch was LLM-assisted,
which wasn't the case.
