arm64: r8a7795 INTC-EX support using RENESAS_IRQC [PATCH 01/02] arm64: dts: r8a7795: Add INTC-EX device node [PATCH 02/02] arm64: renesas: Enable RENESAS_IRQC These two patches add the INTC-EX device node to the r8a7795 DTSI file and selects RENESAS_IRQC to enable the irqchip driver. Those two together allow r8a7795 based platforms to use external interrupt pins IRQ0 -> IRQ5. The patches in this series can be merged independently in any order, but for complete run time support the following two patches are also required: [PATCH] pinctrl: sh-pfc: r8a7795: Add support for INTC-EX IRQ pins [PATCH] clk: shmobile: r8a7795: Add INTC-EX clock The DT compat string "renesas,intc-ex-r8a7795" is already included in Documentation/devicetree/bindings/interrupt-controller/renesas,irqc.txt Tested on r8a7795 Salvator-X by toggling IRQ2 using an external GPIO connected via a loop back adapter on EXIO_D.
