[PATCH 0/2] arm64: dts: renesas: Miscellaneous IPMMU fixes

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This patch series contains two IPMMU-related fixes for the R-Car M3-N
and R-Car H3 ES1.x SoCs.

The first patch is a dependency for a later fix.

Thanks!

[PATCH 1/2] arm64: dts: renesas: r8a77965: Remove non-existent IPMMU-IR

[Geert Uytterhoeven]

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

[Geert Uytterhoeven]

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.
