* [POWERPC] Add of_device_is_available functionJosh Boyer2008-04-06
| | | | | | | | | | | | | | IEEE 1275 defined a standard "status" property to indicate the operational status of a device. The property has four possible values: okay, disabled, fail, fail-xxx. The absence of this property means the operational status of the device is unknown or okay. This adds a function called of_device_is_available that checks the state of the status property of a device. If the property is absent or set to either "okay" or "ok", it returns 1. Otherwise it returns 0. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Add of_get_next_parent()Michael Ellerman2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | 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); } Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: David S.

* [POWERPC] Add of_find_matching_node() helper functionGrant Likely2008-01-16
| | | | | | | | | | | | | | 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.

* [POWERPC] Add for_each_child_of_node() helper for iterating over child nodesMichael Ellerman2007-12-10
| | | | | | | | | Add for_each_child_of_node() to encapsulate the common idiom of iterating over the children of a device_node. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* remove asm/bitops.h includesJiri Slaby2007-10-19
| | | | | | | | | | | | | remove asm/bitops.h includes including asm/bitops directly may cause compile errors. don't include it and include linux/bitops instead. next patch will deny including asm header directly.

* Split out common parts of prom.hStephen Rothwell2007-07-19
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. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Paul Mackerras <paulus@samba.org> Acked-by: David S. Miller <davem@davemloft.net>
