PCI: powerpc: use generic pci_swizzle_interrupt_pin()

2009-01-07T19:12:52+00:00

Use the generic pci_swizzle_interrupt_pin() instead of arch-specific code.

powerpc: Fix IRQ assignment for some PCIe devices

2008-11-30T22:40:18+00:00

Currently, some PCIe devices on POWER6 machines do not get interrupts
assigned correctly.  The problem is that OF doesn't create an
"interrupt" property for them.  The fix is for of_irq_map_pci to fall
back to using the value in the PCI interrupt-pin register in config
space, as we do when there is no OF device-tree node for the device.

I have verified that this works fine with a pair of Squib-E SAS
adapter on a P6-570.

powerpc: Fix OF parsing of 64 bits PCI addresses

2008-07-22T00:39:34+00:00

The OF parsing code for PCI addresses isn't always treating properly
the address space indication 0b11 (ie. 0x3) as meaning 64 bits
memory space.

This means that it fails to parse addresses for PCI BARs that have
this encoding set by the firmware, which happens on some SLOF
versions and breaks offb palette handling on Powerstation.

[POWERPC] Add of_translate_dma_address

2007-12-11T04:43:35+00:00

This adds a variant of of_translate_address that uses the dma-ranges
property instead of "ranges", it's to be used by PCI code in parsing
the dma-ranges property.

Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"

2007-07-26T03:44:36+00:00

This reverts commit fd6e9d3945ee122eb513ada8b17296d243c1ce5e.

Having #size-cells == 0 in a node indicates that things under the
node aren't directly accessible, and therefore we shouldn't try to
translate addresses for devices under the node into CPU physical
addresses.

Some drivers, such as the nvram driver for powermacs, rely on
of_address_to_resource failing if they are called for a node
representing a device whose resources aren't directly accessible
by the CPU.  These drivers were broken by commit fd6e9d39,
resulting in the "Lombard" powerbook hanging early in the boot
process.

[POWERPC] Don't complain if size-cells == 0 in prom_parse()

2007-05-12T01:32:48+00:00

An mdio bus scan was added with ucc_geth phylib
migration patches, now machines complain on boot, saying:

prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@00
prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@01

since size-cells can indeed be 0, this patch fixes the check.
