* irqchip: vic: Convert to handle_domain_irqMarc Zyngier2014-09-031-1/+1
| | | | | | | | Use the new handle_domain_irq method to handle interrupts. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Link: https://lkml.kernel.org/r/1409047421-27649-16-git-send-email-marc.zyngier@arm.com Signed-off-by: Jason Cooper <jason@lakedaemon.net>
* irqchip: vic: Properly chain the cascaded IRQsLinus Walleij2014-04-151-0/+6
| | | | | | | | | | We are flagging the parent IRQ as chained, then we must also make sure to call the chained_irq_[enter|exit] functions for things to work smoothly.

A large chunk of this are clock drivers (bcm281xx, exynos, versatile, shmobile), aside from that, reset controllers for STi as well as a large rework of the Marvell Orion/EBU watchdog driver are notable" * tag 'drivers-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (99 commits) Revert "dts: socfpga: Add DTS entry for adding the stmmac glue layer for stmmac."

| * irqchip: VIC: export vic_init_cascadedArnd Bergmann2014-02-251-0/+1
| | | | | | | | | | | | | | | | vic_init_cascaded is called by integrator impd1 code that can be a loadable module, so the function has to be exported. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
| * irqchip: support cascaded VICsLinus Walleij2014-02-131-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for a VIC to be cascaded off another IRQ. On the Integrator/AP logical module IM-PD1 there is a VIC cascaded off the central FPGA IRQ controller so this is needed for that to work out. In order for the plug-in board to be able to register all the devices with their IRQs relative to the offset of the base obtained for the cascaded VIC, the base IRQ number is passed back to the caller.

| * irqchip: vic: update the base IRQ member correctlyLinus Walleij2014-02-131-1/+5
| | | | | | | | | | | | | | | | | | | | | | When passing 0 as the irq base the VIC driver will dynamically allocate a number of consecutive interrupt descriptors at some available number range. Make sure this number is recorded in the state container rather than the passed-in zero argument in this case.

* | irqchip: Remove asmlinkage from static functionsStephen Boyd2014-03-121-1/+1
|/ | | | | | | | | | | | | | | | | | | | LTO patches add __visible to the asmlinkage define, causing compilation warnings like: drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible' attribute have effect only on public objects [-Wattributes] Drop asmlinkage here to avoid such warnings.

* irqchip: vic: Parse interrupt and resume masks from device treeTomasz Figa2013-09-161-1/+6
| | | | | | | | | | | | This patch extends vic_of_init to parse valid interrupt sources and resume sources masks from device tree. If mask values are not specified in device tree, all sources are assumed to be valid, as before this patch.

* irqchip: Return -EPERM for reserved IRQsGrant Likely2013-06-081-1/+1
| | | | | | | | | | The irqdomain core will report a log message for any attempted map call that fails unless the error code is -EPERM. This patch changes the Versatile irq controller drivers to use -EPERM because it is normal for a subset of the IRQ inputs to be marked as reserved on the various Versatile platforms.
