[POWERPC] Use strcasecmp() rather than strncasecmp() when determining device node compatibility

2007-08-22T05:21:47+00:00

The current code assumes "foo-bar" must always be compatible with a node
compatible with "foo", which breaks device trees where this is not so.

The "case" part is also wrong according to Open Firmware, but it's more
likely to have drivers and/or device trees depending on it, and thus
needs to be handled more carefully.

[POWERPC] Remove get_property and device_is_compatible

2007-08-17T01:01:58+00:00

They were only needed for backwards compatibility and all in tree uses
have now been changed.

[POWERPC] of_detach_node()'s device node argument cannot be const

2007-07-22T11:30:59+00:00

...since it modifies it (when it sets the OF_DETACHED flag).

Consolidate of_find_node_by routines

2007-07-20T03:39:06+00:00

This consolidates the routines of_find_node_by_path, of_find_node_by_name,
of_find_node_by_type and of_find_compatible_device.  Again, the comparison
of strings are done differently by Sparc and PowerPC and also these add
read_locks around the iterations.

Consolidate of_find_property

2007-07-20T03:32:24+00:00

The only change here is that a readlock is taken while the property list
is being traversed on Sparc where it was not taken previously.

Also, Sparc uses strcasecmp to compare property names while PowerPC
uses strcmp.

Consolidate of_device_is_compatible

2007-07-20T03:29:51+00:00

The only difference here is that Sparc uses strncmp to match compatibility
names while PowerPC uses strncasecmp.

Start split out of common open firmware code

2007-07-20T03:28:41+00:00

This creates drivers/of/base.c (depending on CONFIG_OF) and puts
the first trivially common bits from the prom.c files into it.

Split out common parts of prom.h

2007-07-20T03:10:22+00:00

This creates linux/of.h and includes asm/prom.h from it.

We also include linux/of.h from asm/prom.h while we transition.

[POWERPC] Add a warning to help trackdown device_node refcounting bugs

2007-07-10T11:53:47+00:00

When the refcount for a device node goes to 0, we call the
destructor - of_node_release(). This should only happen if we've
already detached the node from the device tree.

So add a flag OF_DETACHED which tracks detached-ness, and if we
find ourselves in of_node_release() without it set, issue a
warning and don't free the device_node. To avoid warning
continuously reinitialise the kref to a sane value.

[POWERPC] Generalise device_node flag interface

2007-07-10T11:53:46+00:00

The struct device_node currently has a _flags variable, although
it's only used for one flag - OF_DYNAMIC.  Generalise the flag
accessors so we can use them with other flags in future.
