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.
Thank you,
Claudiu Beznea
