Driver core: add dev_archdata to struct device Add arch specific dev_archdata to struct device Adds an arch specific struct dev_arch to struct device. This enables architecture to add specific fields to every device in the system, like DMA operation pointers, NUMA node ID, firmware specific data, etc...

[SPARC]: Define minimal struct dev_archdata, similarly to sparc64. Signed-off-by: David S. Miller <davem@davemloft.net> 2007-07-19 07:59:54 +04:00			`#ifndef _ASM_SPARC_DEVICE_H`

sparc/of: Move of_device fields into struct pdev_archdata 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.

of: kill struct of_device Now that the device tree node pointer has been moved out of struct of_device and into the common struct device, there isn't anything unique about of_device anymore. In fact, there isn't much need for a separate of_bus when all busses have access to OF style probing. arch/powerpc and arch/microblaze are moving away from using the of_bus and using the regular platform bus instead for mmio devices. This patch makes of_device the same as platform_device as a stepping stone in migrating of_platform_drivers over to the platform bus.

[SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling. Fully unify all of the DMA ops so that subordinate bus types to the DMA operation providers (such as ebus, isa, of_device) can work transparently. Basically, we just make sure that for every system device we create, the dev->archdata 'iommu' and 'stc' fields are filled in. Then we have two platform variants of the DMA ops, one for SUN4U which actually programs the real hardware, and one for SUN4V which makes hypervisor calls. This also fixes the crashes in parport_pc on sparc64, reported by Meelis Roos. Signed-off-by: David S. Miller <davem@davemloft.net> 2007-07-28 09:39:14 +04:00			`void *iommu;`

of: remove asm/of_device.h It is mostly unused now. Sparc has a few defines left in it, but they can be moved to other headers.

Driver Core: Add platform device arch data V3 Allow architecture specific data in struct platform_device V3. With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices.
