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.

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] mv64x60: Fix FDT compatible names: mv64x60 => mv64360

2008-04-15T11:21:24+00:00

Compatible names should refer to a specific version of the hardware,
without wildcards.  Change each instance of mv64x60 to mv64360, which
is the oldest version we currently support.

[POWERPC] Provide a default irq_host match, which matches on an exact of_node

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

The most common match semantic is an exact match based on the device node.
So provide a default implementation that does this, and hook it up if no
match routine is specified.

[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.
