[POWERPC] Create and hook up of_platform_device_shutdown

2008-02-06T05:29:59+00:00

Although of_platform_device's can have a shutdown routine, at the moment
the bus code doesn't actually call it. So add the required glue to
hook the shutdown routine.

[POWERPC] Add of_get_next_parent()

2008-02-06T05:29:59+00:00

Iterating through a device node's parents is simple enough, but dealing
with the refcounts properly is a little ugly, and replicating that logic
is asking for someone to get it wrong or forget it all together, eg:

while (dn != NULL) {
	/* loop body */
	tmp = of_get_parent(dn);
	of_node_put(dn);
	dn = tmp;
}

So add of_get_next_parent(), inspired by of_get_next_child().  The
contract is that it returns the parent and drops the reference on the
current node, this makes the loop look like:

while (dn != NULL) {
	/* loop body */
	dn = of_get_next_parent(dn);
}

[POWERPC] Add of_find_matching_node() helper function

2008-01-17T03:53:22+00:00

Similar to of_find_compatible_node(), of_find_matching_node() and
for_each_matching_node() allow you to iterate over the device tree
looking for specific nodes, except that they take of_device_id
tables instead of strings.

This also moves of_match_node() from driver/of/device.c to
driver/of/base.c to colocate it with the of_find_matching_node which
depends on it.

[SPARC/64]: Consolidate of_register_driver

2007-10-18T04:17:42+00:00

Also of_unregister_driver.  These will be shortly also used by the
PowerPC code.

Create drivers/of/platform.c

2007-07-20T04:25:51+00:00

and populate it with the common parts from PowerPC and Sparc[64].

Begin consolidation of of_device.h

2007-07-20T03:41:56+00:00

This just moves the common stuff from the arch of_device.h files to
linux/of_device.h.

Begin to consolidate of_device.c

2007-07-20T03:39:59+00:00

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().

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_get_next_child

Consolidate of_get_parent

2007-07-20T03:32:58+00:00

This requires creating dummy of_node_{get,put} routines for sparc and
sparc64.  It also adds a read_lock around the parent accesses.
