1 Socionext SynQuacer External Interrupt Unit (EXIU)
3 The Socionext Synquacer SoC has an external interrupt unit (EXIU)
4 that forwards a block of 32 configurable input lines to 32 adjacent
5 level-high type GICv3 SPIs.
9 - compatible : Should be "socionext,synquacer-exiu".
10 - reg : Specifies base physical address and size of the
12 - interrupt-controller : Identifies the node as an interrupt controller.
13 - #interrupt-cells : Specifies the number of cells needed to encode an
14 interrupt source. The value must be 3.
15 - socionext,spi-base : The SPI number of the first SPI of the 32 adjacent
16 ones the EXIU forwards its interrups to.
20 - Only SPIs can use the EXIU as an interrupt parent.
