Hi,
I've been trying to hook an IRQ on a modified mpc8349emitx board without
success.
The IRQ is hooked physically to IRQ1/GPIO2[13] on the mpc8349e. No other
devices are
tied to this pin.
I'm using uboot 1.2.0 and kernel 2.6.22.19.
Do I need to have a dts entry for this interrupt in order to make
request_irq() succeed?
How can I find the IRQ number? I tried probe_irq_on/off unfortunately it
did not work.
Would it be MPC83xx_IRQ_EXT1 in arch/powerpc/include/asm/mpc83xx.h ?
I'm new doing kernel work. Any hints appreciated.
Oscar
