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>;
|
|
};
