2011-04-20of: Export of_irq_find_parent()Michael Ellerman
We have platform code that needs to find a node's interrupt parent, so export of_irq_find_parent() so we can use it. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2010-10-21of/irq: of_irq.c needs to include linux/irq.hGrant Likely
It works on current architectures simply because asm/prom.h includes it, but it broke when x86 turned on CONFIG_OF. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-10-12of/irq: remove references to NO_IRQ in drivers/of/platform.cAndres Salomon
Instead of referencing NO_IRQ in platform.c, define some helper functions in irq.c to call instead from platform.c. Keep NO_IRQ usage local to irq.c, and define NO_IRQ if not defined in headers.

2010-07-05of/irq: merge irq mapping codeGrant Likely
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.

2010-06-28of/irq: Move irq_of_parse_and_map() to common codeGrant Likely
Merge common code between PowerPC and Microblaze. SPARC implements irq_of_parse_and_map(), but the implementation is different, so it does not use this code.
