2007-07-20Begin consolidation of of_device.hStephen Rothwell
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>
2007-05-07[POWERPC] Export of_device_get_modaliasSylvain Munaut
Apparently other parts of the kernel need to know the modalias internally (like the sysfs code in macintosh driver). To avoid consistency issues, we export this code and use it everywhere it's needed rather than repeat it ...

2007-04-13[POWERPC] Add a unified uevent handler for bus based on of_deviceSylvain Munaut
This common uevent handler allow the several bus types based on of_device to generate the uevent properly and avoiding code duplication. This handlers take a struct device as argument and can therefore be used as the uevent call directly if no special treatment is needed for the bus.

2006-12-04[POWERPC] Refactor 64 bits DMA operationsBenjamin Herrenschmidt
This patch completely refactors DMA operations for 64 bits powerpc. 32 bits is untouched for now. We use the new dev_archdata structure to add the dma operations pointer and associated data to struct device. While at it, we also add the OF node pointer and numa node. In the future, we might want to look into merging that with pci_dn as well. The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced by a set of generic iommu and direct DMA ops (non PCI specific) that can be used by bus types. The toplevel implementation is now inline.

2006-12-04[POWERPC] Souped-up of_platform_device supportBenjamin Herrenschmidt
This patch first splits of_device.c and of_platform.c, the later containing the bits relative to of_platform_device's. On the "breaks" side of things, drivers uisng of_platform_device(s) need to include asm/of_platform.h now and of_(un)register_driver is now of_(un)register_platform_driver. In addition to a few utility functions to locate of_platform_device(s), the main new addition is of_platform_bus_probe() which allows the platform code to trigger an automatic creation of of_platform_devices for a whole tree of devices. The function acts based on the type of the various "parent" devices encountered from a provided root, using either a default known list of bus types that can be "probed" or a passed-in list. It will only register devices on busses matching that list, which mean that typically, it will not register PCI devices, as expected (since they will be picked up by the PCI layer). This will be used by Cell platforms using 4xx-type IOs in the Axon bridge and can be used by any embedded-type device as well.

2006-01-09[PATCH] powerpc: sanitize header files for user space includesArnd Bergmann
include/asm-ppc/ had #ifdef __KERNEL__ in all header files that are not meant for use by user space, include/asm-powerpc does not have this yet. This patch gets us a lot closer there. There are a few cases where I was not sure, so I left them out. I have verified that no CONFIG_* symbols are used outside of __KERNEL__ any more and that there are no obvious compile errors when including any of the headers in user space libraries.
