2011-07-18dt: include linux/errno.h in linux/of_address.hGrant Likely
of_address.h makes reference to some of the error code #defines, so it needs to include errno.h. If CONFIG_PCI is not selected, then some files will fail to compile. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-18of/address: Add of_find_matching_node_by_address helperGrant Likely
of_find_matching_node_by_address() can be used to find a device tree node for a device at a specific address. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-12-23of/address: use proper endianess in get_flagsSebastian Andrzej Siewior
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.

2010-08-01of/address: Clean up function declarationsGrant Likely
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>
2010-07-05of/address: Merge all of the bus translation codeGrant Likely
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.

2010-07-05of/address: merge of_address_to_resource()Grant Likely
Merge common code between PowerPC and Microblaze. This patch also moves the prototype of pci_address_to_pio() out of pci-bridge.h and into prom.h because the only user of pci_address_to_pio() is of_address_to_resource().

2010-07-05of/address: merge of_iomap()Grant Likely
Merge common code between Microblaze and PowerPC. This patch creates new of_address.h and address.c files to containing address translation and mapping routines. First routine to be moved it of_iomap() Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: Michal Simek <monstr@monstr.eu> CC: Stephen Rothwell <sfr@canb.auug.org.au>
