+Amlogic meson GPIO interrupt controller
+
+Meson SoCs contains an interrupt controller which is able watch the SoC pads
+and generate an interrupt on edges or level. The controller is essentially a
+256 pads to 8 GIC interrupt multiplexer, with a filter block to select edge
+or level and polarity. We don't expose all 256 mux inputs because the
+documentation shows that upper part is not mapped to any pad. The actual number
+of interrupt exposed depends on the SoC.
+
+Required properties:
+
+- compatible : should be "amlogic,meson-gpio-interrupt".
+- reg : Specifies base physical address and size of the registers.
+- interrupts : list of GIC interrupts which can be used with the
+ GPIO IRQ multiplexer
+
+Example:
+
+gpio_irq@9880 {
+ compatible = "amlogic,meson-gpio-interrupt";
+ reg = <0x0 0x09880 0x0 0x10>;
+ interrupts = <GIC_SPI 64 IRQ_TYPE_NONE>,
+ <GIC_SPI 65 IRQ_TYPE_NONE>,
+ <GIC_SPI 66 IRQ_TYPE_NONE>,
+ <GIC_SPI 67 IRQ_TYPE_NONE>,
+ <GIC_SPI 68 IRQ_TYPE_NONE>,
+ <GIC_SPI 69 IRQ_TYPE_NONE>,
+ <GIC_SPI 70 IRQ_TYPE_NONE>,
+ <GIC_SPI 71 IRQ_TYPE_NONE>;
+ };
Add the DT node for GPIO IRQ support on AMlogic Meson GX.
