This interrupt controller is found in Microchip SoCs (SAMA7G5) and provides
|
|
support for handling up to 2 external interrupt lines.

is the trigger type as defined in interrupt.txt present in this directory.

description: |
|
|
Contains the GIC SPI IRQs mapped to the external interrupt lines. They
|
|
should be specified sequentially from output 0 to output 1.
