powerpc: Convert i8259_lock to raw_spinlock

2010-02-19T03:52:31+00:00

i8259_lock needs to be a real spinlock in RT. Convert it to
raw_spinlock.

2010-02-17T03:02:48+00:00

Now we use printf style alignment there is no need to manually space
these fields.

powerpc: Make "intspec" pointers in irq_host->xlate() const

2009-12-09T06:10:37+00:00

Writing a driver using SCLPC on the MPC5200B I detected, that the
intspec arrays to map irqs to Linux virq cannot be const, because the
mapping and xlate functions only take non const pointers. All those
functions do not modify the intspec, so a const pointer could be used.

powerpc: Fixup last users of irq_chip->typename

2009-11-24T03:32:45+00:00

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

powerpc: Remove get_irq_desc()

2009-10-30T06:20:55+00:00

get_irq_desc() is a powerpc-specific version of irq_to_desc(). That
is reason enough to remove it, but it also doesn't know about sparse
irq_desc support which irq_to_desc() does (when we enable it).

powerpc: Fix irq_alloc_host() reference counting and callers

2008-06-09T03:51:16+00:00

When I changed irq_alloc_host() to take an of_node
(52964f87c64e6c6ea671b5bf3030fb1494090a48: "Add an optional
device_node pointer to the irq_host"), I botched the reference
counting semantics.

Stephen pointed out that it's irq_alloc_host()'s business if
it needs to take an additional reference to the device_node,
the caller shouldn't need to care.

[POWERPC] i8259: Add disable method

2007-11-08T03:15:29+00:00

Since commit 76d2160147f43f982dfe881404cfde9fd0a9da21, the NE2000 card
is not working anymore on PPC and POWERPC and produces WATCHDOG
timeouts.

The patch below fixes that the same way it has been done on x86, x86_64
and MIPS.

[POWERPC] Add an optional device_node pointer to the irq_host

2007-09-13T15:33:20+00:00

The majority of irq_host implementations (3 out of 4) are associated
with a device_node, and need to stash it somewhere. Rather than having
it somewhere different for each host, add an optional device_node pointer
to the irq_host structure.

[POWERPC] Fix CHRP platforms with only 8259

2006-10-25T03:49:22+00:00

On CHRP platforms with only a 8259 controller, we should set the
default IRQ host to the 8259 driver's one for the IRQ probing
fallbacks to work in case the IRQ tree is incorrect (like on
Pegasos for example). Without this fix, we get a bunch of WARN_ON's
during boot.

[POWERPC] Fix up after irq changes

2006-10-07T12:08:26+00:00

Remove struct pt_regs * from all handlers.
Also remove the regs argument from get_irq() functions.
Compile tested with arch/powerpc/config/* and
arch/ppc/configs/prep_defconfig
