Hi Geert,

Ouch please ignore this patch.

Now I know where I missed the v2 combining "[PATCH 01/16] dt-bindings:
arm: renesas: Document Renesas RZ/V2L SoC" and "[PATCH 02/16]
dt-bindings: arm: renesas: Document SMARC EVK". I picked a wrong
commit-id vehicle sending a v2!

This patch is intended for internal build testing atm. We are yet to
test r9a07g044c1/r9a07g054l1 on actual HW.

Sorry about the inconvenience.

Cheers,
Prabhakar
