[PATCH 00/15] Add support for Renesas RZ/V2N SoC and EVK

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj at 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

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.
- Enabling RZ/V2N SoC support in `arm64 defconfig`.

These patches have been tested on the RZ/V2N EVK with v6.14,
