It also has a 32-bit LPDDR4 interface and video codec (H.264). The RZ/V2M is used with ISP firmware that runs on one of the Cortex-A53 cores. The firmware is an integral part of the SoC such that the HW User's Manual documents which of the peripheral modules are used by the firmware. Initial patches enables minimal peripherals on Renesas RZ/V2M EVK board and booted via nfs. Ethernet is broadly compatible with the etheravb-rcar-gen3 driver, but interrupts need some work so it's not been included in this patch set. Below blocks are enabled on Renesas RZ/V2M EVK board: - memory - External input clock - CPG - UART Links for SoC and EVK: [*] https://www.renesas.com/us/en/products/microcontrollers-microprocessors/rz-cortex-a-mpus/rzv2m-dual-cortex-a53-lpddr4x32bit-ai-accelerator-isp-4k-video-codec-4k-camera-input-fhd-display-output Sorry for cross posting the patches to multiple subsystems, as these are just the dt-binding patches included as part of initial bringup patches.
