Add a function to create amba_devices (i.e. primecell peripherals)

peripheral id value.Based on the original work by Jeremy Kerr.

of_platform_populate() is similar to of_platform_bus_probe() except
that it strictly enforces that all device nodes must have a compatible

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

This patch drops the reference to a global 'cmd_line' variable from
early_init_dt_scan_chosen, and instead passes the pointer to the command
line string via the *data argument. Each architecture does something
slightly different with the initial command line, so it makes sense for
the architecture to be able to specify the variable name.Signed-off-by: Grant Likely

Commit e2f2a93b, "of/promtree: add package-to-path support to pdt"
changed dp->name from using the 'name' property to using
package-to-path. This fixed /proc/device-tree creation by eliminating
conflicts between names (the 'name' property provides names like
'battery', whereas package-to-path provides names like
'/foo/bar/battery@0', which we stripped to 'battery@0'). However, it
also breaks of_device_id table matching.The fix that we _really_ wanted was to keep dp->name based upon
the name property ('battery'), but based dp->full_name upon
package-to-path ('battery@0'). This patch does just that.This changes all users (except SPARC) of promtree to use the full
result from package-to-path for full_name, rather than stripping the
directory out. In practice, the strings end up being exactly the
same; this change saves time, code, and memory.SPARC continues to use the existing build_path_component() code.
v2: combine two patches and revert of_pdt_node_name to original version
v3: use dp->phandle instead of passing around node
v4: warn/bail out for non-sparc archs if pkg2path is not set
v5: split of_pdt_build_full_name into sparc & non-sparc versions
v6: Pass NULL to pkg2path before buf gets assigned.
Drop check for pkg2path hook on each and every node.
v7: Don't BUG() when unable to get the full_path; create a
known-unique name instead.Signed-off-by: Andres Salomon

drivers/of/{platform,device}.c and into ibmebus.c where it is actually

ibmebus_bus_* to reflect the actual usage.This patch is part of moving all of the of_platform_bus_type users

x86_of_pci_init() does two things:
- it provides a generic irq enable and disable function. enable queries
the device tree for the interrupt information, calls ->xlate on the
irq host and updates the pci->irq information for the device.- it walks through PCI bus(es) in the device tree and adds its children
(device) nodes to appropriate pci_dev nodes in kernel. So the dtb
node information is available at probe time of the PCI device.Adding a PCI bus based on the information in the device tree is
currently not supported. Right now direct access via ioports is used.Signed-off-by: Sebastian Andrzej Siewior
