irq_domain/powerpc: Replace custom xlate functions with library functions

2012-02-16T13:11:24+00:00

This patch converts a number of the powerpc drivers to use the common library
of irq_domain xlate functions, dropping a bunch of lines in the process.

v5: - Remove tsi108 changes from patch

irq_domain: Replace irq_alloc_host() with revmap-specific initializers

2012-02-16T13:11:22+00:00

Each revmap type has different arguments for setting up the revmap.
This patch splits up the generator functions so that each revmap type
can do its own setup and the user doesn't need to keep track of how
each revmap type handles the arguments.

This patch also adds a host_data argument to the generators.  There are
cases where the host_data pointer will be needed before the function returns.
ie. the legacy map calls the .map callback for each irq before returning.

v2: - Add void *host_data argument to irq_domain_add_*() functions
    - fixed failure to compile
    - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c

irq_domain/powerpc: Use common irq_domain structure instead of irq_host

2012-02-14T21:06:50+00:00

This patch drops the powerpc-specific irq_host structures and uses the common
irq_domain strucutres defined in linux/irqdomain.h.  It also fixes all
the users to use the new structure names.

Renaming irq_host to irq_domain has been discussed for a long time, and this
patch is a step in the process of generalizing the powerpc virq code to be
usable by all architecture.

An astute reader will notice that this patch actually removes the irq_host
structure instead of renaming it.  This is because the irq_domain structure
already exists in include/linux/irqdomain.h and has the needed data members.

driver-core: remove sysdev.h usage.

2011-12-22T00:26:03+00:00

The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.

The sysdev code will be going away soon, so this include needs to be
removed no matter what.

locking, powerpc: Annotate uic->lock as raw

2011-09-13T09:12:10+00:00

uic->lock is protecting the interrupt controller hardware. This lock
can not be preempted on -rt.

In mainline this change documents the low level nature of
the lock - otherwise there's no functional difference. Lockdep
and Sparse checking will work as usual.

powerpc: uic: Cleanup flow type handling

2011-03-29T12:48:10+00:00

The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus. The core also
updates IRQ_LEVEL.

Use irq_data to get the level type information in the chip functions.
