2007-10-17[SPARC/64]: Consolidate of_register_driverGravatar Stephen Rothwell 1-0/+21
Also of_unregister_driver. These will be shortly also used by the PowerPC code. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-20Create drivers/of/platform.cGravatar Stephen Rothwell 2-1/+97
and populate it with the common parts from PowerPC and Sparc[64]. 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>
2007-07-20Begin consolidation of of_device.hGravatar Stephen Rothwell 1-1/+1
This just moves the common stuff from the arch of_device.h files to linux/of_device.h. 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>
2007-07-20Begin to consolidate of_device.cGravatar Stephen Rothwell 3-0/+135
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().

2007-07-20Consolidate of_find_node_by routinesGravatar Stephen Rothwell 1-0/+115
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.

2007-07-20Consolidate of_get_next_childGravatar Stephen Rothwell 1-0/+24
This adds a read_lock around the child/next accesses on Sparc. 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>
2007-07-20Consolidate of_get_parentGravatar Stephen Rothwell 1-0/+21
This requires creating dummy of_node_{get,put} routines for sparc and sparc64. It also adds a read_lock around the parent accesses. 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>
2007-07-20Consolidate of_find_propertyGravatar Stephen Rothwell 1-0/+26
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. 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>
2007-07-20Consolidate of_device_is_compatibleGravatar Stephen Rothwell 1-0/+24
The only difference here is that Sparc uses strncmp to match compatibility names while PowerPC uses strncasecmp. 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>
2007-07-20Start split out of common open firmware codeGravatar Stephen Rothwell 2-0/+66
This creates drivers/of/base.c (depending on CONFIG_OF) and puts the first trivially common bits from the prom.c files into it. 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>
