Subject: [PATCH 0/6] Add CANFD support for Renesas R9A09G056/057/077/087 SoCs

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This series of patches adds support for the CANFD controller on the
Renesas RZ/V2H(P) (R9A09G057), RZ/V2N (R9A09G056), RZ/T2H (R9A09G077),
and RZ/N2H (R9A09G087) SoCs. It includes the addition of CANFD nodes in
the respective SoC DTSI files, as well as enabling the CANFD controller
on the RZ/T2H and RZ/N2H evaluation kits. For RZ/V2H(P) and RZ/V2N, the
CANFD controller can be used on the PMOD connector using an external
CAN transceiver.

Note,
1] This patch series applies on top of the series [0]
2] The CANFD DT binding and driver changes have been posted separately [1].
