Subject: [PATCH v4 08/10] riscv: dts: renesas: Add minimal DTS for Renesas RZ/Five SMARC EVK
Date: Tue, 20 Sep 2022 19:49:02 +0100	[thread overview]
Message-ID: <20220920184904.90495-9-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20220920184904.90495-1-prabhakar.mahadev-lad.rj@bp.renesas.com>

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Enable the minimal blocks required for booting the Renesas RZ/Five
SMARC EVK with initramfs.

Below are the which are enabled:
- CPG
- CPU0
- DDR (memory regions)
- PINCTRL
- PLIC
- SCIF0

As we are reusing the RZ/G2UL SMARC SoM [0] and carrier [1] board DTSIs
which enables almost all the blocks supported by the RZ/G2UL SoC and
whereas on RZ/Five SoC we will be gradually adding the blocks hence the
aliases for ETH and I2C are deleted as support for these blocks is not
yet enabled on RZ/Five SoC.

---
v3 -> v4
* Dropped deleting place holder nodes
* Updated SW1 settings comment
* Update commit message

v2 -> v3
* Dropped RB tags from Conor and Geert
* Now re-using the SoM and carrier board DTS/I from RZ/G2UL

v1 -> v2
* New patch
