of: Add device tree selftests

2011-12-12T20:40:16+00:00

Add some runtime test cases for the library of device tree parsing functions.

v2: - Add testcase for phandle with 0 args
    - Don't run testcases if testcase data isn't present in device tree

pci/of: Match PCI devices to OF nodes dynamically

2011-06-07T23:08:17+00:00

powerpc has two different ways of matching PCI devices to their
corresponding OF node (if any) for historical reasons. The ppc64 one
does a scan looking for matching bus/dev/fn, while the ppc32 one does a
scan looking only for matching dev/fn on each level in order to be
agnostic to busses being renumbered (which Linux does on some
platforms).

This removes both and instead moves the matching code to the PCI core
itself. It's the most logical place to do it: when a pci_dev is created,
we know the parent and thus can do a single level scan for the matching
device_node (if any).

The benefit is that all archs now get the matching for free. There's one
hook the arch might want to provide to match a PHB bus to its device
node. A default weak implementation is provided that looks for the
parent device device node, but it's not entirely reliable on powerpc for
various reasons so powerpc provides its own.

of/pci: move of_irq_map_pci() into generic code

2011-02-04T18:46:50+00:00

There is a tiny difference between PPC32 and PPC64. Microblaze uses the
PPC32 variant.

	block to function implementation, fixed for non ppc and microblaze

of/net: Move of_get_mac_address() to a common source file.

2010-11-01T05:08:14+00:00

There are two identical implementations of of_get_mac_address(), one
each in arch/powerpc/kernel/prom_parse.c and
arch/microblaze/kernel/prom_parse.c.  Move this function to a new
common file of_net.{c,h} and adjust all the callers to include the new
header.

of/promtree: make drivers/of/pdt.c no longer sparc-only

2010-10-11T03:53:30+00:00

Clean up pdt.c:
 - make build dependent upon config OF_PROMTREE
 - #ifdef out the sparc-specific stuff
 - create pdt-specific header

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: Move irq_of_parse_and_map() to common code

2010-06-28T19:41:33+00:00

Merge common code between PowerPC and Microblaze.  SPARC implements
irq_of_parse_and_map(), but the implementation is different, so it
does not use this code.

openfirmware: Add OF phylib support code

2009-04-27T09:53:47+00:00

Add support for parsing the device tree for PHY devices on an MDIO bus.
Currently many of the PowerPC ethernet drivers are open coding a solution
for reading data out of the device tree to find the correct PHY device.
This patch implements a set of common routines to:

a) let MDIO bus drivers register phy_devices described in the tree, and
b) let MAC drivers find the correct phy_device via the tree.

spi: Add OF binding support for SPI busses

2008-07-26T02:34:40+00:00

This patch adds support for populating an SPI bus based on data in the
OF device tree.  This is useful for powerpc platforms which use the
device tree instead of discrete code for describing platform layout.
