No this is not how you pass a number of IRQs in the device tree.

"interrupts" is an array. Pass every interrupt here for a full
resolution of the IRQs.

Further this looks fishy:

+ interrupts = <42>;

Usually you pass flags with the IRQs, I would rather have expected
an array like this:

interrupts = < 90 0x4 96 0x4 14 0x4 15 0x4 79 0x4>;

0x4 is IRQ_TYPE_LEVEL_HIGH, you can use the dts
#include <dt-bindings/interrupt-controller/irq.h> and
define that symbolically.

Doesn't the DaVinci IRQ controller support *any* IRQ flags?

Since the driver code is not reading out the interrupts but
(I guess?) falling back to platform data IRQ assignment,
this seems wrong.
