Hi All,

This patch series adds initial support for Renesas RZ/G2L SoC and
Renesas RZ/G2L SMARC EVK.

The RZ/G2L SoC includes a single/dual Cortex-A55 CPU including
below list of IP's:
* Cortex-M33
* 3D Graphics engine (Arm Mali-G31)
* Video Codec (H.264)
* Camera interface (MIPI-CSI or Parallel-IF)
* Display interface (MIPI-DSI or Parallel-IF)
* USB2.0 interface 2ch, SD interface 2ch
* CAN interface (CAN-FD)
* Giga bit Ethernet 2ch

Initial patches enables minimal peripherals on Renesas RZ/G2L
SMARC EVK and booted via initramfs.
* Documentation for RZ/G2{L,LC,UL} SoC variants
* SoC identification support
* CPG core support
* Minimal SoC DTSi
* Minimal DTS for SMARC EVK

Patches are based on top of [1] master branch.
