From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> This patch series adds initial support for the Renesas RZ/V2N (R9A09G056) SoC and its evaluation board (EVK). The Renesas RZ/V2N is a vision AI microprocessor (MPU) designed for power-efficient AI inference and real-time vision processing. It features Renesas' proprietary AI accelerator (DRP-AI3), delivering up to 15 TOPS AI performance, making it ideal for applications such as Driver Monitoring Systems (DMS), industrial monitoring cameras, and mobile robots. Key features of the RZ/V2N SoC: Processing Power: - Quad Arm Cortex-A55 cores at 1.8GHz for high-performance computing - Single Arm Cortex-M33 core at 200MHz for real-time processing - 1.5MB on-chip SRAM for fast data access - LPDDR4/LPDDR4X memory interface for high-speed RAM access AI and Vision Processing: - DRP-AI3 accelerator for low-power, high-efficiency AI inference - Arm Mali-C55 ISP (optional) for image signal processing - Dual MIPI CSI-2 camera interfaces for multi-camera support High-Speed Interfaces: - PCIe Gen3 (2-lane) 1ch for external device expansion - USB 3.2 (Gen2) 1ch (Host-only) for high-speed data transfer - USB 2.0 (Host/Function) 1ch for legacy connectivity - Gigabit Ethernet (2 channels) for network communication Industrial and Automotive Features: - 6x CAN FD channels for automotive and industrial networking - 24-channel ADC for sensor data acquisition LINK: https://tinyurl.com/renesas-rz-v2n-soc The series introduces: - Device tree bindings for various subsystems (SYS, SCIF, SDHI, CPG, pinctrl). - RZ/V2N SoC identification support. - Clock and pinctrl driver updates for RZ/V2N. - Initial DTSI and device tree for the RZ/V2N SoC and EVK. These patches have been tested on the RZ/V2N EVK with v6.15-rc1 kernel, logs can be found here: https://gist.github.com/prabhakarlad/aa3da7558d007aab8a288550005565d3 @Geert, Ive rebased the patches on top of v6.15-rc1 + renesas-dts-for-v6.16 + renesas-clk-for-v6.16 branches. Also these patches apply on top of the below series [1] and [2]. I had to sort the order in Makefile for patch [3] to avoid conflicts. [1] https://lore.kernel.org/all/20250401090133.68146-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ [2] https://lore.kernel.org/all/20250403212919.1137670-1-thierry.bultel.yh@bp.renesas.com/#t [3] https://lore.kernel.org/all/20250403212919.1137670-13-thierry.bultel.yh@bp.renesas.com/ Note, dtbs_check will generate the below warnings this is due to missing ICU support as part of initial series. I will be sending a follow-up patch series to add ICU support which will fix these warnings. arch/arm64/boot/dts/renesas/r9a09g056n48-rzv2n-evk.dtb: pinctrl@10410000 (renesas,r9a09g056-pinctrl): 'interrupt-controller' is a required property from schema $id: http://devicetree.org/schemas/pinctrl/renesas,rzg2l-pinctrl.yaml# arch/arm64/boot/dts/renesas/r9a09g056n48-rzv2n-evk.dtb: pinctrl@10410000 (renesas,r9a09g056-pinctrl): '#interrupt-cells' is a required property from schema $id: http://devicetree.org/schemas/pinctrl/renesas,rzg2l-pinctrl.yaml# v1->v2: - Added acks from Rob. - Squashed the RZ/V2N EVK and SoC variant documentation into a single commit. - Updated the commit messages. - Added RZV2N_Px, RZV2N_PORT_PINMUX, and RZV2N_GPIO macros in SoC DTSI as we are re-using renesas,r9a09g057-pinctrl.h in pictrl driver hence to keep the consistency with the RZ/V2H(P) SoC these macros are added. - Dropped `renesas,r9a09g056-pinctrl.h` header file. - Followed DTS coding style guidelines - Dropped defconfig changes from the series. - Dropped SDHI dt-binding patch as its already applied to mmc -next tree.
