of/address: Merge all of the bus translation code

2010-07-05T22:14:26+00:00

Microblaze and PowerPC share a large chunk of code for translating
OF device tree data into usable addresses.  Differences between the two
consist of cosmetic differences, and the addition of dma-ranges support
code to powerpc but not microblaze.  This patch moves the powerpc
version into common code and applies many of the cosmetic (non-functional)
changes from the microblaze version.

of/address: merge of_address_to_resource()

2010-07-05T22:14:26+00:00

Merge common code between PowerPC and Microblaze.  This patch also
moves the prototype of pci_address_to_pio() out of pci-bridge.h and
into prom.h because the only user of pci_address_to_pio() is
of_address_to_resource().

of/address: merge of_iomap()

2010-07-05T22:14:26+00:00

Merge common code between Microblaze and PowerPC.  This patch creates
new of_address.h and address.c files to containing address translation
and mapping routines.  First routine to be moved it of_iomap()

of/irq: merge irq mapping code

2010-07-05T22:14:25+00:00

Merge common irq mapping code between PowerPC and Microblaze.

This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one().  The functions are dependent on one another, so all
three are merged in a single patch.  Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.

of_irq_to_resource() is also merged, but in this case the
implementations are different.  This patch drops the microblaze version
and uses the powerpc implementation unchanged.  The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do.  Therefore the powerpc version is safe to adopt.

of/powerpc: Move Powermac irq quirk code into powermac pic driver code

2010-07-05T22:14:25+00:00

The code that figures out what is wrong with the powermac irq device
tree data belongs with the rest of the powermac irq code.  This patch
moves it out of prom_parse.c and into powermac/pic.c so that it is only
compiled in when actually needed.

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.
