[PATCH 1/3] arm64: dts: renesas: r8a77965: Remove non-existent IPMMU-IR

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

The R-Car Gen3 HardWare Manual Errata for Rev. 1.00 (Aug 24, 2018)
removed the IPMMU-IR IOMMU instance on R-Car M3-N, as this SoC does not
have an Image Processing Unit (IMP-X5) nor the A3IR power domain.

[PATCH 2/3] arm64: dts: renesas: r8a7795-es1: Add missing power domains to IPMMU nodes

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

While commit 3b7e7848f0e88b36 ("arm64: dts: renesas: r8a7795: Add IPMMU
device nodes") for R-Car H3 ES2.0 did include power-domains properties,
they were forgotten in the counterpart for older R-Car H3 ES1.x SoCs.
