[PATCH v2 09/10] arm64: dts: renesas: ironhide: Enable SCMI devpd, sys, clock, and reset

From: Geert Uytterhoeven

Date: Wed Jul 08 2026 - 06:28:15 EST


SCP FW SDKv4.28.0 and later for Renesas R-Car X5H Ironhide not only
implement the SCMI base protocol, but also the SCMI power domain, system
power, clock, and reset domain management protocols.

Enable support for the latter by adding the corresponding SCMI protocol
subnodes.

v2:
- Fix misindentations,
- Add scmi_clk node, as it is no longer added in earlier commits.
