I have a chip connected on the PCI bus on an MPC512x, but if I get the
IRQ property from the PCI chip, it is not set up by Linux.
The IRQ line goes directly from the chip to the MPC512x uc, so I don't
know if I should create a separate node just to get the interrupt, or I
should expect the pci functions to assign it an interrupt based on the
PCI bus.
The description for the PCI bus is like this:
pci: [EMAIL PROTECTED] {
interrupt-map-mask = <0xf800 0x0 0x0 0x7>;
interrupt-map = <
// IDSEL 0x15 - Slot PCI
0xa800 0x0 0x0 0x1 &ipic 0x0 0x8
0xa800 0x0 0x0 0x2 &ipic 0x1 0x8
0xa800 0x0 0x0 0x3 &ipic 0x2 0x8
0xa800 0x0 0x0 0x4 &ipic 0x3 0x8
>;
interrupt-parent = < &ipic >;
interrupts = <17 0x8>;
bus-range = <0 0>;
ranges = <0x42000000 0x0 0xa0000000 0xa0000000 0x0
0x10000000
0x02000000 0x0 0xb0000000 0xb0000000 0x0
0x10000000
0x01000000 0x0 0x00000000 0x84000000 0x0
0x01000000>;
clock-frequency = <66000000>;
#interrupt-cells = <1>;
#size-cells = <2>;
#address-cells = <3>;
reg = <0x80008500 0x100>;
compatible = "fsl,mpc5121-pci";
device_type = "pci";
};
Thanks,
Matteo
