of/address: Add reg-names property to name an iomem resource

2012-01-04T07:27:22+00:00

Add a reg-names property to allow for reg regions to be reference by name instead of by index. Some devices have multiple register regions which are more naturally referenced by name. If the name is available, use it to name the resource when creating a devices. Otherwise keep the device name.

of: address: use resource_size helper

2011-08-01T11:55:02+00:00

that should be the approved way of calculating the size of resources. No functional changes. Cc: Grant Likely Signed-off-by: Felipe Balbi Signed-off-by: Grant Likely

of/address: Add of_find_matching_node_by_address helper

2011-07-18T22:32:26+00:00

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

of/address: use proper endianess in get_flags

2010-12-23T22:57:48+00:00

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: use __be32 types for big-endian device tree data

2010-10-13T03:58:42+00:00

Use the sparse annotations so we can keep track of endianness. Signed-off-by: Jeremy Kerr Signed-off-by: Grant Likely

of: Use full node name in resource structures

2010-07-05T22:14:27+00:00

Resource names appear in human readable output, so when extracting IRQ and address resources from a device tree node, use the full node name to give proper context in places like /proc/iomem.

of/address: restrict 'no-ranges' kludge to powerpc

2010-07-05T22:14:27+00:00

Certain Apple machines don't use the ranges property correctly, but the workaround should not be applied on other architectures. This patch disables the workaround for non-powerpc architectures. Signed-off-by: Grant Likely Acked-by: Benjamin Herrenschmidt CC: Stephen Rothwell

of/address: little-endian fixes

2010-07-05T22:14:27+00:00

Fix some endian issues in the OF address translation code. Signed-off-by: Grant Likely Acked-by: Benjamin Herrenschmidt CC: Michal Simek CC: Stephen Rothwell

of/address: Merge all of the bus translation code

2010-07-05T22:14:26+00:00

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/address: merge of_address_to_resource()

2010-07-05T22:14:26+00:00

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().
