2016-11-29powerpc/virtex: Use generic xilinx irqchip driverZubair Lutfullah Kakakhel1-209/+2
The Xilinx interrupt controller driver is now available in drivers/irqchip. Switch to using that driver.

2015-09-16genirq: Remove irq argument from irq flow handlersThomas Gleixner1-1/+1
Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!

2015-05-11powerpc: Constify irq_domain_opsKrzysztof Kozlowski1-1/+1
The irq_domain_ops are not modified by the driver and the irqdomain core code accepts pointer to a const data. Signed-off-by: Krzysztof Kozlowski <[email protected]> Signed-off-by: Michael Ellerman <[email protected]>
2014-09-25powerpc: make of_device_ids constUwe Kleine-König1-1/+1
of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. This allows to mark all struct of_device_id const, too. While touching these line also put the __init annotation at the right position where necessary.

2013-11-11powerpc: add missing explicit OF includes for ppcRob Herring1-0/+1
Commit b5b4bb3f6a11f9 (of: only include prom.h on sparc) removed implicit includes of of_*.h headers by powerpc's prom.h. Some components were missed in initial clean-up patch, so add the necessary includes to fix powerpc builds.

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 <[email protected]> Cc: Rob Herring <[email protected]> Cc: Benjamin Herrenschmidt <[email protected]> Cc: Thomas Gleixner <[email protected]> Cc: Milton Miller <[email protected]> Tested-by: Olof Johansson <[email protected]>
2012-02-14irq_domain/powerpc: Use common irq_domain structure instead of irq_hostGrant Likely1-8/+8
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.

2011-03-29powerpc: xilinx: Cleanup flow type handlingThomas Gleixner1-6/+0
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 the LEVEL flag. Signed-off-by: Thomas Gleixner <[email protected]>

2009-12-09powerpc: Make "intspec" pointers in irq_host->xlate() constRoman Fietze1-1/+1
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. Signed-off-by: Roman Fietze <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>

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).

2009-05-14powerpc/virtex: Fix duplicate level irq events.John Linn1-10/+107
