* powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell2008-08-03
| | | | | | | | | | | | | | from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] ibmebus: Move to of_device and of_platform_driver, match eHCA and ↵Joachim Fenkes2007-10-17
| | | | | | | | | | | | | | eHEA drivers Replace struct ibmebus_dev and struct ibmebus_driver with struct of_device and struct of_platform_driver, respectively. Match the external ibmebus interface and drivers using it.

* [POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanupJoachim Fenkes2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds two sysfs attributes to /sys/bus/ibmebus which can be used to notify the ebus driver of added / removed ebus devices in the OF device tree. Echoing the device's location code (as found in the OFDT "ibm,loc-code" property) into the "probe" attribute will notify ebus of addition of the device and cause the appropriate device driver's probe function to be called on the device. Likewise, echoing the location code into the "remove" attribute will cause the device to be removed from the system. The writes will block until the respective operation has finished and return an error code if the operation failed. In addition, two minor tidbits are fixed: - The fake root device used to provide a common parent for all ebus devices is now based on device instead of of_device - it had no associated devtree node. This saves several checks throughout the ebus driver. - The sysfs attributes are now generated automagically by device_register() instead of by the ibmebus code, which saves a few compiler warnings about unused return codes.

* [POWERPC] Refactor 64 bits DMA operationsBenjamin Herrenschmidt2006-12-04
| | | | | | | | | | | | | | | | | 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.

* IRQ: Use the new typedef for interrupt handler function pointersDavid Howells2006-10-09
| | | | | | | | | | | | | | | | Use the new typedef for interrupt handler function pointers rather than actually spelling out the full thing each time. This was scripted with the following small shell script: #!/bin/sh egrep -nHrl -e 'irqreturn_t[ ]*[(][*]' $* | while read i do echo $i perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $? done Signed-Off-By: David Howells <dhowells@redhat.com>

* [POWERPC] Constify & voidify get_property()Jeremy Kerr2006-07-31
| | | | | | | | | | | Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powerpc core changes. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: sanitize header files for user space includesArnd Bergmann2006-01-08
| | | | | | | | | | | | | | | 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.

* [PATCH] powerpc: IBMEBUS bus supportHeiko J Schick2006-01-08
This patch adds the necessary core bus support used by device drivers that sit on the IBM GX bus on modern pSeries machines like the Galaxy infiniband for example. It provide transparent DMA ops (the low level driver works with virtual addresses directly) along with a simple bus layer using the Open Firmware matching routines.
