x86, irq, devicetree: Use common irqdomain map interface to program IOAPIC pins

2014-06-21T21:05:43+00:00

Refine devicetree to use common irqdomain map interface to program
IOAPIC pins, so we can unify the callsite to progam IOAPIC pins.

x86, devicetree, irq: Use common mechanism to support irqdomain

2014-06-21T21:05:43+00:00

Now the ioapic driver provides a common interface to create irqdomain,
so replace the private implementation.

x86, irq: Enhance mp_register_ioapic() to support irqdomain

2014-06-21T21:05:42+00:00

Enhance function mp_register_ioapic() to support irqdomain.
When registering IOAPIC, caller may provide callbacks and parameters
for creating irqdomain. The IOAPIC core will create irqdomain later
if caller has passed in corresponding parameters.

x86, irq: Count legacy IRQs by legacy_pic->nr_legacy_irqs instead of NR_IRQS_LEGACY

2014-06-21T21:05:42+00:00

Some platforms, such as Intel MID and mshypv, do not support legacy
interrupt controllers. So count legacy IRQs by legacy_pic->nr_legacy_irqs
instead of hard-coded NR_IRQS_LEGACY.

x86: use FDT accessors for FDT blob header data

2014-04-30T05:59:19+00:00

Remove the direct accesses to FDT header data using accessor
function instead. This makes the code more readable and makes the FDT
blob structure more opaque to the arch code. This also prepares for
removing struct boot_param_header completely.

of/irq: Create of_irq_parse_and_map_pci() to consolidate arch code.

2013-10-24T10:50:36+00:00

Several architectures open code effectively the same code block for
finding and mapping PCI irqs. This patch consolidates it down to a
single function.

of/irq: simplify args to irq_create_of_mapping

2013-10-24T10:42:57+00:00

All the callers of irq_create_of_mapping() pass the contents of a struct
of_phandle_args structure to the function. Since all the callers already
have an of_phandle_args pointer, why not pass it directly to
irq_create_of_mapping()?

of/irq: Replace of_irq with of_phandle_args

2013-10-24T10:42:51+00:00

struct of_irq and struct of_phandle_args are exactly the same structure.
This patch makes the kernel use of_phandle_args everywhere. This in
itself isn't a big deal, but it makes some follow-on patches simpler.
