* powerpc+of: Move of_drconf_cell struct definition to asm/prom.hNathan Fontenot2012-11-14
| | | | | | | | | | This patch moves the definition of the of_drconf_cell struct to asm/prom.h to make it available for all powerpc/pseries code.

* pci/of: Match PCI devices to OF nodes dynamicallyBenjamin Herrenschmidt2011-06-07
| | | | | | | | | | | | | | | | | | | | | | | | powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

* of/pci: move of_irq_map_pci() into generic codeSebastian Andrzej Siewior2011-02-04
| | | | | | | | | | | There is a tiny difference between PPC32 and PPC64. Microblaze uses the PPC32 variant.

* of/address: use proper endianess in get_flagsSebastian Andrzej Siewior2010-12-23
| | | | | | | | | | | | | | This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and such. Those variables are pointing to the device tree which contains integers in big endian format. Most functions are doing it right because of_read_number() is doing the right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and of_bus_isa_map() were accessing the data directly and were doing it wrong.

* of/net: Move of_get_mac_address() to a common source file.David Daney2010-11-01
| | | | | | | | | | | | There are two identical implementations of of_get_mac_address(), one each in arch/powerpc/kernel/prom_parse.c and arch/microblaze/kernel/prom_parse.c. Move this function to a new common file of_net.{c,h} and adjust all the callers to include the new header.

* of/address: Clean up function declarationsGrant Likely2010-08-01
| | | | | | | | | | | | This patch moves the declaration of of_get_address(), of_get_pci_address(), and of_pci_address_to_resource() out of arch code and into the common linux/of_address header file. This patch also fixes some of the asm/prom.h ordering issues. It still includes some header files that it ideally shouldn't be, but at least the ordering is consistent now so that of_* overrides work. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* of: remove asm/of_platform.hGrant Likely2010-07-24

* of/address: Merge all of the bus translation codeGrant Likely2010-07-05
| | | | | | | | | | | | | | | Microblaze and PowerPC share a large chunk of code for translating OF device tree data into usable addresses. Differences between the two consist of cosmetic differences, and the addition of dma-ranges support code to powerpc but not microblaze. This patch moves the powerpc version into common code and applies many of the cosmetic (non-functional) changes from the microblaze version.

* of/irq: merge irq mapping codeGrant Likely2010-07-05
| | | | | | | | | | | | | | | | | | | | | Merge common irq mapping code between PowerPC and Microblaze. This patch merges of_irq_find_parent(), of_irq_map_raw() and of_irq_map_one(). The functions are dependent on one another, so all three are merged in a single patch. Other than cosmetic difference (ie. DBG() vs. pr_debug()), the implementations are identical. of_irq_to_resource() is also merged, but in this case the implementations are different. This patch drops the microblaze version and uses the powerpc implementation unchanged. The microblaze version essentially open-coded irq_of_parse_and_map() which it does not need to do. Therefore the powerpc version is safe to adopt.

| | | | | | | | | | | | The code that figures out what is wrong with the powermac irq device tree data belongs with the rest of the powermac irq code.

| | | | | | | | | | | | | | | | | | | | | In preparation to prune things out of the Sparc, PowerPC and Microblaze asm/prom.h files, change the #include statements to ensure that even if asm/prom.h is included first, linux/of.h gets to determine the order in which files are processed. This patch adds a #include <linux/of.h> to each of the prom.h files *above* the multi-include protection macros to ensure that linux/of.h can define things before prom.h gets processed. At the end of the merge the cross dependencies between the files should be gone and a sane #include scheme can be restored. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.
