    Subject[PATCH 0/4] Add new Renesas RZ/V2H SoC
    Date
    From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

    Hi,

    This patch series adds initial support for RZ/V2H{P} (R9A09G057) SoC
    identification.

    The RZ/V2H{P} SoC is equipped with a Quad 64-bit Arm Cortex-A55 core
    (up to 1.8 GHz), dual 32-bit Arm Cortex R8 core (up to 800 MHz) and a
    32-bit Arm Cortex M33 core (up to 200 MHz). It supports the below
    IP blocks/Features:
    - Boot
    * Selectable boot CPU from Cortex-M33 or Cortex-A55
    - Accelerated engines
    * AI accelerator (dynamically reconfigurable processor for AI (DRP-AI))
    * Dynamic re-configurable processor (DRP)
    * 3D graphics engine (GE3D MALI-G31) (optional)
    * Image signal processing (ISP MALI-C55) (optional)
    * Image scaling unit (ISU)
    * Video codec unit (VCU)
    - On-chip SRAM and external memory interfaces
    * On-chip share SRAM (6-Mbyte with ECC)
    * 2-channel memory controller for LPDDR4-3200 or LPDDR4X-3200 with a
    32-bit bus width
    * xSPI interface
    * SDHI (eMMC/SD - 3ch)
    - Timers
    * 32-bit general purpose timers (16 ch)
    * 32-bit CMTW (8 ch)
    * 32-bit GTM (8 ch)
    * RTC
    * WDT (4 ch)
    - Communication/storage /network interface
    * Ethernet (2 ch: 10/100/1000 BASE)
    * USB2.0 (1 ch: Host/Function, 1 ch: Host only)
    * USB3.2 Gen2 (2 ch: Host only)
    * PCIe Gen3 (1/2/4 lanes)
    * MIPI CSI2 (4 ch: 1/2/4 lanes)
    * MIPI DSI (1ch: 1/2/4 lanes)
    * CAN/CANFD (6 ch)
    * SCI (10 ch: UART/SPI/I2C)
    * SCIF (1 ch)
    * SPI (3 ch)
    * I2C (9 ch)
    * I3C (1 ch)
    - Audio
    * Asynchronous sampling rate converter unit (SCU) (up to 192 kHz)
    * DMAC for Audio (ADMAC) is available to transfer audio formats
    of I2S with SCU.
    * Flexible audio clock generator (ADG) for audio functions.
    * I2S (TDM) input/output interfaces (half-duplex 10 ch.; full-duplex
    5 ch.)
    * SPDIF input/output interfaces (3 ch.)
    * Pulse density modulation (PDM) input interfaces (6 ch.)
    - Analogue/Digital converter and sensors
    * 2.5 Msps 12-bit ADC (8 ch)
    * Internal temperature sensors (2 ch)
    - Security
    * Hardware cryptographic engine (optional)
