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>;
	};
