Allwinner A20/A31 SoCs have a special interrupt controller for managing NMI. Three register are present to (un)mask, control and acknowledge NMI. These two patches add a new irqchip driver in cascade with GIC. Changes since v1: - added binding document Changes since v2: - fixed trigger type in DTS - new explanations in binding documentation - added support for A31 (sun6i) Changes since v3: - changed compatibles Changes since v4: - fixed binding documentation Changes since v5: - switched to handle_fasteoi_irq handler to avoid the double interrupts issue Carlo Caione (3): ARM: sun7i/sun6i: irqchip: Add irqchip driver for NMI controller ARM: sun7i/sun6i: dts: Add NMI irqchip support ARM: sun7i/sun6i: irqchip: Update the documentation .../allwinner,sun67i-sc-nmi.txt | 27 +++ arch/arm/boot/dts/sun6i-a31.dtsi | 9 + arch/arm/boot/dts/sun7i-a20.dtsi | 9 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-sunxi-nmi.c | 208 +++++++++++++++++++++ 5 files changed, 254 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/allwinner,sun67i-sc-nmi.txt create mode 100644 drivers/irqchip/irq-sunxi-nmi.c -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
