2018-09-07of: make default address and size cells sizes privateRob Herring
Only some old OpenFirmware implementations rely on default sizes. Any FDT and modern implementation should have explicit properties. Make the OF_ROOT_NODE_*_CELLS_DEFAULT defines private so we don't get any outside users. This also gets us one step closer to removing the asm/prom.h dependency on Sparc. Cc: "David S.

2014-05-18sparc: drop use of extern for prototypes in arch/sparc/include/asmSam Ravnborg
Drop extern for all prototypes and adjust alignment of parameters as required after the removal. In a few rare cases adjust linelength to conform to maximum 80 chars, and likewise in a few rare cases adjust alignment of parameters to static functions.

2013-10-09of: move of_address_to_resource and of_iomap declarations from sparcRob Herring
Move of_address_to_resource and of_iomap declarations to common code. These only differ on sparc, but the declarations are the same and don't need to be in arch header.

2012-11-23of/address: sparc: Declare of_iomap as an extern function for sparc againAndreas Larsson
This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.

2012-11-09of/address: sparc: Declare of_address_to_resource() as an extern function ↵Andreas Larsson
for sparc again This bug-fix makes sure that of_address_to_resource is defined extern for sparc so that the sparc-specific implementation of of_address_to_resource() is once again used when including include/linux/of_address.h in a sparc context. A number of drivers in mainline relies on this function working for sparc. The bug was introduced in a850a7554442f08d3e910c6eeb4ee216868dda1e, "of/address: add empty static inlines for !CONFIG_OF". Contrary to that commit title, the static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never defined for sparc. This is good behavior for the other functions in include/linux/of_address.h, as the extern functions defined in drivers/of/address.c only gets linked when OF_ADDRESS is configured. However, for of_address_to_resource there exists a sparc-specific implementation in arch/sparc/arch/sparc/kernel/of_device_common.c Solution suggested by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Andreas Larsson <andreas@gaisler.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: David S.

2012-02-26irq_domain: Centralize definition of irq_dispose_mapping()Grant Likely
Several architectures define their own empty irq_dispose_mapping(). Since the irq_domain code is centralized now, there is little need to do so. This patch removes them and creates a new empty copy when !CONFIG_IRQ_DOMAIN is selected. The patch also means that IRQ_DOMAIN becomes selectable on all architectures.

2010-07-24of: remove asm/of_device.hGrant Likely
It is mostly unused now. Sparc has a few defines left in it, but they can be moved to other headers.

2009-10-15of: Rework linux/of.h and asm/prom.h include orderingGrant Likely
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.

Stephen Rothwell noticed that I committed an earlier version of the patch that didn't have two things fixed: 1) irq_of_parse_and_map() should return "unsigned int" not "int" and it should return zero for "no irq" 2) irq_dispose_mapping() should be an inline function, not a macro, for type checking With feedback and suggestions from Anton Vorontsov.

2008-08-24sparc: Add mutex for set property calls.David S. Miller
On some platforms, the I2C controller is shared between the OS and OBP. OBP uses this I2C controller to access the EEPROM, and thus is programmed when the kernel calls prom_setprop(). Wrap such calls with the new of_set_property_mutex. Relevant I2C bus drivers can grab this mutex around top-level I2C operations to provide the proper protection. Signed-off-by: David S.
