Hi Cesar,

The SPI Interrupts are also mentioned in the table, they are at Interrupt IDs 204, 205 and 206 respectively for each of the instances.

There is an offset of 32 between what is used in the Linux GIC500 device-tree bindings and what is defined in the TRM. The first GIC_SPI interrupt has the Interrupt ID of 32, and Linux Device-Tree values are indexed from 0.

Please see the GIC500 devicetree bindings document at <Linux-Kernel>/Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml for further details.

regards

Suman
