From: Lad Prabhakar Date: Mon, 8 Sep 2025 09:39:30 +0000 (+0100) Subject: dt-bindings: i3c: renesas,i3c: Add RZ/V2H(P) and RZ/V2N support X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c5d0df4945085098e4778b27267a225efacf4d2a;p=thirdparty%2Fkernel%2Fstable.git dt-bindings: i3c: renesas,i3c: Add RZ/V2H(P) and RZ/V2N support Add device tree binding support for the I3C Bus Interface on Renesas RZ/V2H(P) and RZ/V2N SoCs. The I3C IP on these SoCs is identical to that found on the RZ/G3E SoC. Add new compatible strings "renesas,r9a09g056-i3c" for RZ/V2N and "renesas,r9a09g057-i3c" for RZ/V2H(P). Both variants use "renesas,r9a09g047-i3c" as a fallback compatible to indicate hardware compatibility with the RZ/G3E implementation. Update the title to be more generic as it now covers multiple SoC families beyond just RZ/G3S and RZ/G3E.
