Socionext SynQuacer External Interrupt Unit (EXIU)
|
|
|
|
The Socionext Synquacer SoC has an external interrupt unit (EXIU)
|
|
that forwards a block of 32 configurable input lines to 32 adjacent
|
|
level-high type GICv3 SPIs.
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be "socionext,synquacer-exiu".
|
|
- reg : Specifies base physical address and size of the
|
|
control registers.
|
|
- interrupt-controller : Identifies the node as an interrupt controller.
|
|
- #interrupt-cells : Specifies the number of cells needed to encode an
|
|
interrupt source. The value must be 3.
|
|
- socionext,spi-base : The SPI number of the first SPI of the 32 adjacent
|
|
ones the EXIU forwards its interrups to.
|
|
|
|
Notes:
|
|
|
|
- Only SPIs can use the EXIU as an interrupt parent.
|
|
|
|
Example:
|
|
|
|
exiu: interrupt-controller@510c0000 {
|
|
compatible = "socionext,synquacer-exiu";
|
|
reg = <0x0 0x510c0000 0x0 0x20>;
|
|
interrupt-controller;
|
|
interrupt-parent = <&gic>;
|
|
#interrupt-cells = <3>;
|
|
socionext,spi-base = <112>;
|
|
};
