Hello,
Can u give me an example with a single IRQ of a configuration-node for a
dts?
[EMAIL PROTECTED] {
interrupts = 1 2 3;
interrupt-parent = mpc5200_pic;
};
Ahh - oh weh - so simple! Thank you!
The interrupts property matches the size of the #interrupt-cells

I have a newbie question which I never had properly answered. On the
MPC52xx and specifically regarding the device tree, how are interrupt
numbers assigned?
On Efika (and in the DT docs) it's basically the X Y Z where X is the
type

The l2 irq numbers map directly to the interrupt
Hello,
I have looked up kernel/irq/manage.c. -ENOSYS is returned on function
setup_irq because the used irq(MPC52xx_IRQ2) is the same as no_irq_chip.
THE MPC52xx_IRQ2 is a excerpt from include/ppc/mpc52xx.h (per copy
paste), but mpc52xx is (now) a powerpc-arch. What is the desired value

Dear Linux-enthusiasts,
I'm still at the same problem.
I have now implemented a irq_chip for the hardwired IRQ2. Now I have:
--==
volatile static struct mpc52xx_intr __iomem *intr;
unsigned long flags;
static DEFINE_SPINLOCK(my_irq_controller_lock);
/*
* HELPER-Function
*/
static inline

You probably don't want to do this (unless you are cascading IRQs to
custom external hardware). All

Hello all.
What are the steps to configure an MPC500B-Board to react on an IRQ (2)?
I have written a test-driver with this code-snippets, but the prozessor
hangs when loading the driver.
my __init-function looks like:
static int __init mod_init( void )
{
volatile static struct
