MPC85xx External/Internal Interrupts

[Alemao]

I've read some posts in the list, and about:

irq_of_parse_and_map()
irq_create_map()

But Im still trying to understand MPC85xx TSEC1 dts.

Gianfar driver is using request_irq(), and request_irq() uses virtual
irq, right?

Thats why in dts all irqs for TSEC1 are "offseted" of 16?

Manual  |  DTS
---------------
13         29
14         30
18         34

And about external IRQs, MPC8555RM doesnt have IDs for them, what
should I use to request IRQ0 using irq_create_map()??

In MPC83xx all interrupts have IDs, including IRQ0, IRQ1...
That make things much more clear.

Thanks in advance,
