Hi, This patch adds support for Microchip External Interrupt Controller present on SAMA7G5. The controller supports for 2 external interrupt lines, glitch filter capabilities and is connected to GIC as follows: pinX +------+ EXT_IRQ0 +------+ int 153 (for pinX) +------+ ------>| |--------->| |------------------->| | pinY | PIO | EXT_IRQ1 | EIC | int 154 (for pinY) | GIC | ------>| |--------->| |------------------->| | +------+ +------+ +------+ where PIO is the pin controller.
