Hi!
On my MPC8439 based board, running Linux 2.6.18 with ARCH=powerpc, the
IRQ's for the I2C behave in a for me mysterious way.
In my DTS file, I have the following:
[EMAIL PROTECTED] {
device_type = "i2c";
compatible = "fsl-i2c";
reg = <3000 100>;
interrupts = <e 8>;
interrupt-parent = <&/[EMAIL PROTECTED]/[EMAIL PROTECTED]>;
dfsrr;
};
[EMAIL PROTECTED] {
device_type = "i2c";
compatible = "fsl-i2c";
reg = <3000 100>;
interrupts = <f 8>;
interrupt-parent = <&/[EMAIL PROTECTED]/[EMAIL PROTECTED]>;
dfsrr;
};
But when I boot the system and cat /proc/interrupts, the output says:
18: 61 IPIC Level i2c-mpc
19: 0 IPIC Level i2c-mpc
This doesn't make sense to me. Why are the IRQ numbers changed? They are
still adjacent, so it seems to be some logic to the change. Does anyone
know what this is?
Cheers // Fredrik Roubert
