Hi All,

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

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

Changes for v3:
* Updated tag from Rob for CPG binding doc
* Included RB tags from Geert
* Added description for clock-names property in CPG binding doc
* Dropped serial driver patch (already merged)
* Fixed CPG core issues for USB/ADC IP
* Added r9a07g044l2.dtsi

Changes for v2:
* Included type-2 RZ/G2Ul SoC in binding doc
* Added single entry for SMARC EVK "renesas,smarc-evk"
* Renamed ARCH_R9A07G044L to ARCH_R9A07G044 and
  dropped ARCH_R9A07G044LC config
* Dropped SoC identification changes will post them as
  separate patch.
* Updated comment in sh-sci.c
* Binding documentation patch for serial driver has been
  accepted so dropped the patch from this series
* Incorporated changes requested by Geert for CPG core
* Fixed dtbs_check errors
* Dropped 'clock-names'/'clocks'/'power-domains'/'resets'
  properties from GIC node and will include them in a separate
  patch along with arm,gic-v3.yaml binding updates
* Included ACK's from Rob

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