of: Provide default of_node_to_nid() implementation.

2010-07-30T06:03:58+00:00

of_node_to_nid() is only relevant in a few architectures.  Don't force
everyone to implement it anyway.

of/sparc: move is_root_node() to of.h

2010-07-14T23:08:03+00:00

Rename is_root_node() to of_node_is_root() and make it available for
all archs to use, as it's not PROM-specific.

of: Fix comparison of "compatible" properties

2010-03-18T13:30:31+00:00

Commit 7c7b60cb87547b1664a4385c187f029bf514a737
"of: put default string compare and #a/s-cell values into common header"

Breaks various things on powerpc due to using strncasecmp instead of
strcasecmp for comparing against "compatible" strings.

This causes things like the 4xx PCI code to fail miserably due to the
partial matches in code like this:

       for_each_compatible_node(np, NULL, "ibm,plb-pcix")
               ppc4xx_probe_pcix_bridge(np);
       for_each_compatible_node(np, NULL, "ibm,plb-pci")
               ppc4xx_probe_pci_bridge(np);

It's not quite right to do partial name match. Entries in a compatible
list are meant to be matched whole. If a device is compatible with both
"foo" and "foo1", then the device should have both strings in its
"compatible" property.

This patch reverts powerpc and microblaze us to use strcasecmp.

of/sparc: Remove sparc-local declaration of allnodes and devtree_lock

2010-02-14T20:02:44+00:00

Both allnodes and devtree_lock are defined in common code.  The
extern declaration should be in the common header too so that the
compiler can type check.  allnodes is already in of.h, but
devtree_lock should be declared there too.

This patch removes the SPARC declarations and uses decls in of.h instead.

of: move definition of of_chosen into common code.

2010-02-14T14:13:55+00:00

Rather than defining of_chosen in each arch, it can be defined for all
in driver/of/base.c

of: put default string compare and #a/s-cell values into common header

2010-02-14T14:13:50+00:00

Most architectures don't need to change these.  Put them into common
code to eliminate some duplication

of: protect linux/of.h with CONFIG_OF

2010-02-14T14:13:43+00:00

For platforms that have CONFIG_OF optional, we need to make the contents
of linux/of.h conditional on CONFIG_OF.

of: Remove old and misplaced function declarations

2010-02-14T14:13:38+00:00

The following functions don't exist:
  finish_device_tree()
  print_properties()
  prom_n_intr_cells()
  prom_get_irq_senses()

The following functions are in drivers/of/base.c, so the declaration
belongs in of.h instead of of_fdt.h
  of_machine_is_compatible()
  prom_add_property()
  prom_remove_property()
  prom_update_property()

of: use __be32 for cell value accessors

2010-02-09T15:34:10+00:00

Currently, we're using u32 for cell values, and hence assuming
host-endian device trees.

As we'd like to support little-endian platforms, use a __be32 for cell
values, and convert in the cell accessors.

of: make set_node_proc_entry private to proc_devtree.c

2010-02-09T15:34:10+00:00

We only need set_node_proc_entry in proc_devtree.c, so move it there.

This fixes the !HAVE_ARCH_DEVTREE_FIXUPS build, as we can't make make
the definition in linux/of.h conditional on this #define (definitions in
asm/prom.h can't be exposed to linux/of.h, due to the enforced #include
ordering).
