2012-04-15sparc32: rename sparc_irq_config to sparc_configSam Ravnborg
This struct holds platform specific config and is thus not limited to irq stuff. Do not let the name confuse us to think this is irq only. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-10-31sparc: remove several unnecessary module.h include instancesPaul Gortmaker
Building an allyesconfig doesn't reveal a hidden need for any of these. Since module.h brings in the whole kitchen sink, it just needlessly adds 30k+ lines to the cpp burden. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-03-16sparc32: introduce build_device_irqSam Ravnborg
build_device_irq() is used to encapsulate the plaform specific details when we build an irq. For now the default is a simple 1:1 but sun4d differs. This patch refactors functionality - but does not change the existing functionality. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-07-24sparc: remove references to of_device and to_of_deviceGrant Likely
of_device is just a #define alias to platform_device. This patch replaces all references to it with platform_device. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
2010-07-24of: Merge of_platform_bus_type with platform_bus_typeGrant Likely
of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
2010-06-28sparc/of: Move of_device fields into struct pdev_archdataGrant Likely
This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2010-05-18of: eliminate of_device->node and dev_archdata->{of,prom}_nodeGrant Likely
This patch eliminates the node pointer from struct of_device and the of_node (or prom_node) pointer from struct dev_archdata since the node pointer is now part of struct device proper when CONFIG_OF is set, and all users of the old pointer locations have already been converted over to use device->of_node. Also remove dev_archdata_{get,set}_node() as it is no longer used by anything. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-05-18of: Always use 'struct device.of_node' to get device node pointer.Grant Likely
The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead. (struct of_device *)->node (struct dev_archdata *)->prom_node (sparc) (struct dev_archdata *)->of_node (powerpc & microblaze) Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-04-28driver-core: Add device node pointer to struct deviceGrant Likely
Currently, platforms using CONFIG_OF add a 'struct device_node *of_node' to dev->archdata. However, with CONFIG_OF becoming generic for all architectures, it makes sense for commonality to move it out of archdata and into struct device proper. This patch adds a struct device_node *of_node member to struct device and updates all locations which currently write the device_node pointer into archdata to also update dev->of_node. Subsequent patches will modify callers to use the archdata location and ultimately remove the archdata member entirely.

2010-01-28of: unify phandle name in struct device_nodeGrant Likely
In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2009-08-17sparc,leon: Added support for AMBAPP bus.Konrad Eisele
The device is a AMBA bus if it is a child of prom node "ambapp" (AMBA plug and play). Two functions leon_trans_init() and leon_node_init() (defined in sparc/kernel/leon_kernel.c) are called in the prom_build_tree() path if CONFIG_SPARC_LEON is defined. leon_node_init() will build up the device tree using AMBA plug and play. Also: a extra check was addes to prom_common.c:build_one_prop() in case a rom-node is undefined which can happen for SPARC-LEON because it creates only a minimum nodes to emulate sparc behaviour.

2009-06-16sparc: move of_device common code to of_device_commonRobert Reif
This patch moves code common to of_device_32.c and of_device_64.c into of_device_common.h and of_device_common.c. The only functional difference is in sparc32 where of_bus_default_map is used in place of of_bus_sbus_map because they are equivelent. There is still room for further code consolidation with some minor refactoring. Boot tested on sparc32 and compile tested on sparc64.

2009-04-22sparc: Fix bus type probing for ESP and LE devices.David S. Miller
If there is a dummy "espdma" or "ledma" parent device above ESP scsi or LE ethernet device nodes, we have to match the bus as SBUS. Otherwise the address and size cell counts are wrong and we don't calculate the final physical device resource values correctly at all. Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling of LANCE and ESP parent nodes in of_device.c") was meant to fix this problem, but that only influences the inner loop of build_device_resources(). We need this logic to also kick in at the beginning of build_device_resources() as well, when we make the first attempt to determine the device's immediate parent bus type for 'reg' property element extraction.
