Subject: [PATCH v3 06/10] riscv: dts: renesas: Add initial devicetree for Renesas RZ/Five SoC
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
Add initial device tree for Renesas RZ/Five RISC-V CPU Core (AX45MP
Single).
Below is the list of IP blocks added in the initial SoC DTSI which can be
used to boot via initramfs on RZ/Five SMARC EVK:
- AX45MP CPU
- CPG
- PINCTRL
- PLIC
- SCIF0
- SYSC

v2->v3
* Fixed clock entry for CPU core
* Fixed timebase frequency to 12MHz
* Fixed sorting of the nodes
* Included RB tags
v1->v2
* Dropped including makefile change
* Updated ndev count
