+UniPhier AIDET
+
+UniPhier AIDET (ARM Interrupt Detector) is an add-on block for ARM GIC (Generic
+Interrupt Controller). GIC itself can handle only high level and rising edge
+interrupts. The AIDET provides logic inverter to support low level and falling
+edge interrupts.
+
+Required properties:
+- compatible: Should be one of the following:
+ "socionext,uniphier-ld4-aidet" - for LD4 SoC
+ "socionext,uniphier-pro4-aidet" - for Pro4 SoC
+ "socionext,uniphier-sld8-aidet" - for sLD8 SoC
+ "socionext,uniphier-pro5-aidet" - for Pro5 SoC
+ "socionext,uniphier-pxs2-aidet" - for PXs2/LD6b SoC
+ "socionext,uniphier-ld11-aidet" - for LD11 SoC
+ "socionext,uniphier-ld20-aidet" - for LD20 SoC
+ "socionext,uniphier-pxs3-aidet" - for PXs3 SoC
+- reg: Specifies offset and length of the register set for the device.
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an interrupt
+ source. The value should be 2. The first cell defines the interrupt number
+ (corresponds to the SPI interrupt number of GIC). The second cell specifies
+ the trigger type as defined in interrupts.txt in this directory.
+
+Example:
+
+ aidet: aidet@5fc20000 {
+ compatible = "socionext,uniphier-pro4-aidet";
+ reg = <0x5fc20000 0x200>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ };
