-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>;
-	};
