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 treeSigned-off-by: Grant Likely

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.Signed-off-by: Benjamin Herrenschmidt

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.Signed-off-by: David Daney

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.Signed-off-by: Grant Likely

Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for
the i2c API". If i2c-core is compiled as a module, the helper needs
to be compiled as a module, as well. Rename i2c.c to of_i2c.c to
avoid name space conflict.[paulus@samba.org: Changed dependency from OF to PPC_OF to avoid

This implements various helpers to support OF bindings for the GPIO
LIB API.Previously this was PowerPC specific, but it seems this code isn't
arch-dependent anyhow, so let's place it into of/.SPARC will not see this addition yet, real hardware seem to not use
GPIOs at all. But this might change:http://www.leox.org/docs/faq_MLleon.html
"16-bit I/O port" sounds promising. :-)

This moves all the common parts for the Sparc, Sparc64 and PowerPC
of_device.c files into drivers/of/device.c.Apart from the simple move, Sparc gains of_match_node() and a call to
of_node_put in of_release_dev(). PowerPC gains better recovery if
device_create_file() fails in of_device_register().Signed-off-by: Stephen Rothwell
