The pegaos board needs an irq quirk in pata_via.
Where is the quirk list for libata? I dont see one in pata_via.c
drivers/ide/pci/via82cxxx.c:init_hwif_via82cxxx()
440 #ifdef CONFIG_PPC_CHRP
441 if(machine_is(chrp) && _chrp_type == _CHRP_Pegasos) {
442 hwif->irq = hwif->channel ? 15 : 14;
443 }
444 #endif
This is in the firmware node. Will a fixup of the 'interrupts' property
work or does everything poke directly at the PCI registers?
Should fixup_device_tree_chrp() take care of the 'interrupts' property?
