* [SPARC]: Fix serial console device detection.David S. Miller2007-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | The current scheme works on static interpretation of text names, which is wrong. The output-device setting, for example, must be resolved via an alias or similar to a full path name to the console device. Paths also contain an optional set of 'options', which starts with a colon at the end of the path. The option area is used to specify which of two serial ports ('a' or 'b') the path refers to when a device node drives multiple ports. 'a' is assumed if the option specification is missing. This was caught by the UltraSPARC-T1 simulator. The 'output-device' property was set to 'ttya' and we didn't pick upon the fact that this is an OBP alias set to '/virtual-devices/console'. Instead we saw it as the first serial console device, instead of the hypervisor console. The infrastructure is now there to take advantage of this to resolve the console correctly even in multi-head situations in fbcon too. Thanks to Greg Onufer for the bug report.

* Consolidate of_find_node_by routinesStephen Rothwell2007-07-19
| | | | | | | | | | | 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_parentStephen Rothwell2007-07-19
| | | | | | | | | 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>
* Consolidate of_find_propertyStephen Rothwell2007-07-19
| | | | | | | | | | | | 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.

* Consolidate of_device_is_compatibleStephen Rothwell2007-07-19
| | | | | | | | | 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>
* Start split out of common open firmware codeStephen Rothwell2007-07-19
| | | | | | | | | 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>
* 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>

* [SPARC64]: of_device layer IRQ resolutionDavid S. Miller2006-06-29
| | | | | | | | | | | | | | | | | | Do IRQ determination generically by parsing the PROM properties, and using IRQ controller drivers for final resolution. One immediate positive effect is that all of the IRQ frobbing in the EBUS, ISA, and PCI controller layers has been eliminated. We just look up the of_device and use the properly computed value. The PCI controller irq_build() routines are gone and no longer used. Unfortunately sbus_build_irq() has to remain as there is a direct reference to this in the sunzilog driver. That can be killed off once the sparc32 side of this is written and the sunzilog driver is transformed into an "of" bus driver. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC]: Beginnings of generic of_device framework.David S. Miller2006-06-29
| | | | | | | | | | The idea is to fully construct the device register and interrupt values into these of_device objects, and convert all of SBUS, EBUS, ISA drivers to use this new stuff. Much ideas and code taken from Ben H.'s powerpc work. Signed-off-by: David S. Miller <davem@davemloft.net>
