Nicolas Ferre <nicolas.ferre@atmel.com> writes:

   A series about interrupt controller cleanup. AT91 AIC is moving to
   fasteoi type of handler and sparse IRQ.
   The Device Tree support is added to take into account priority
   and external IRQ.
   In addition to that, the new AIC5 IP is introduced.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>

8 = active low level-sensitive.
Valid combinations are 1, 2, 3, 4, 8.
Default flag for internal sources should be set to 4 (active high).
The third cell is used to specify the irq priority from 0 (lowest) to 7
(highest).
- reg: Should contain AIC registers location and length
