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)
