Hi All,

RZ/V2L is equipped with a Cortex-A55 (1.2 GHz) CPU and built-in AI
accelerator "DRP-AI" for vision, which is Renesas' original technology.
It also has a 16-bit DDR3L/DDR4 interface and a built-in 3D graphics
engine with Arm Mali-G31 and video codec (H.264).

The RZ/V2L is also package- and pin-compatible with the RZ/G2L. This
allows RZ/G2L users to easily upgrade to the RZ/V2L for additional AI
functions without needing to modify the system configuration, keeping
migration costs low.

Initial patches enables minimal peripherals on Renesas RZ/V2L SMARC EVK
and booted via initramfs/nfs. Below blocks are enabled on Renesas RZ/V2L
SMARC EVK:
- memory
- External input clock
- CPG
- Pin controller
- SCIF
- GbEthernet
- Audio Clock

Sorry for cross posting the patches to multiple subsystems, as these are
just the dt-binding patches included as part of initial bringup patches.
