[PATCH v4 07/10] riscv: dts: r9a07g043: Add placeholder nodes

From: Prabhakar
Date: Tue Sep 20 2022 - 14:51:12 EST


From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Add empty placeholder nodes to RZ/Five (R9A07G043) SoC DTSI.

This is in preparation to reuse the RZ/G2UL SMARC SoM and carrier board
DTSIs([0] and [1]).

As the RZ/G2UL SMARC EVK enables almost all the blocks supported by the
SoC and whereas for the RZ/Five SMARC EVK we will gradually be enabling
the blocks as a result we are adding the placeholder nodes to avoid DTB
compilation errors (currently we dont have support in DTC to delete the
reference nodes without actual nodes).

[1] arch/arm64/boot/dts/renesas/rzg2ul-smarc.dtsi

---
v3 -> v4
* Dropped status and reg-names properties
* Updated the commit message
* Note sbc node is not enabled in RZ/G2UL SMARC EVK but will be soon
enabled so added a placeholder for this too.

v2 -> v3
* New patch
