2012-02-16irq_domain: Replace irq_alloc_host() with revmap-specific initializersGrant Likely1-3/+2
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 Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>
2012-02-15irq_domain/powerpc: Use common irq_domain structure instead of irq_hostGrant Likely1-4/+4
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.

2009-10-30powerpc: Remove get_irq_desc()Michael Ellerman1-1/+1
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).

2008-04-15[POWERPC] mv64x60: Fix FDT compatible names: mv64x60 => mv64360Mark A. Greer1-2/+2
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.

2007-09-13[POWERPC] Provide a default irq_host match, which matches on an exact of_nodeMichael Ellerman1-6/+0
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. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-09-13[POWERPC] Add an optional device_node pointer to the irq_hostMichael Ellerman1-5/+3
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.

2007-05-12[POWERPC] Add interrupt support for Marvell mv64x60 chipsDale Farnsworth1-0/+305
There are 3 interrupt groups each with its own status/mask registers. We use a separate struct irq_chip for each interrupt group and handle interrupts in two stages or levels: level 1 selects the appropriate struct irq_chip, and level 2 selects individual interrupts within that irq_chip.
