[PATCH 0/3] arm64: dts: renesas: Add INTC-EX device node on R-Car M3-W, V3M, and D3

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This patch series adds device nodes for the Interrupt Controller for
External Devices (INTC-EX) to the DT sources for the R-Car M3-W, V3M, and
D3 SoCs.

This has been tested on Salvator-X with R-Car M3-W.
(FWIW, I also tested on Salvator-XS with H3 ES2.0).

The compatible values used depend on the DT binding update "[PATCH]
dt-bindings: irqchip: renesas-irqc: Document R-Car M3-W, V3M, D3 support",
but they are non-controversial.

Actual use may depend on pinctrl patches (e.g. "[PATCH 2/3] pinctrl:
sh-pfc: r8a7796: Add support for INTC-EX IRQ pins").

Thanks!

[PATCH 1/3] arm64: dts: r8a7796: Add INTC-EX device node

[Geert Uytterhoeven]

Add a device node for the Interrupt Controller for External Devices
(INTC-EX) on R-Car M3-W, which serves external IRQ pins IRQ[0-5].

     triggering.
