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>; |
|
};
