Subject: Re: IRQ2-4 number to use on mpc83xx?
Date: Tue, 23 Sep 2008 11:08:53 +0200 [thread overview]
Message-ID: <48D8B225.4000709@matrix-vision.de> (raw)
In-Reply-To: <062501c91d03$0c46be40$24d43ac0$@se>
I can only tell how I do on MPC834x :
Table 8-6. IVEC/CVEC/MVEC Field Definition
Interrupt ID Number Interrupt Meaning
17 IRQ1
18 IRQ2
19 IRQ3
20 IRQ4
21 IRQ5
22 IRQ6
23 IRQ7
48 IRQ0
Given this I can use this dts section for PCI devices connected @ IRQ0
and IRQ1
interrupt-map = <0x5800 0 0 1 &ipic 0x30 0x8
0x6000 0 0 1 &ipic 0x11 0x8
0x6000 0 0 2 &ipic 0x11 0x8>;
You should be able to use IRQ-Nr 18-20 for IRQ2-4.
regards,
Andre
