2018-03-20genirq: Add missing SPDX identifiersThomas Gleixner
Add SPDX identifiers to files - which contain an explicit license boiler plate or reference - which do not contain a license reference and were not updated in the initial SPDX conversion because the license was deduced by the scanners via EXPORT_SYMBOL_GPL as GPL2.0 only. [ tglx: Moved adding identifiers from the patch which removes the references/boilerplate ] Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Kate Stewart <kstewart@linuxfoundation.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Philippe Ombredanne <pombredanne@nexb.com> Link: https://lkml.kernel.org/r/20180314212030.668321222@linutronix.de

2015-05-22genirq: Set IRQCHIP_SKIP_SET_WAKE for no_irq_chipGeert Uytterhoeven
If no_irq_chip is used for wake up (e.g. gpio-keys with a simple GPIO controller), the following warning is printed on resume from s2ram: WANING: CPU: 0 PID: 1046 at kernel/irq/manage.c:537 irq_set_irq_wake+0x9c/0xf8() Unbalanced IRQ 113 wake disable This happens because no_irq_chip does not implement irq_chip.irq_set_wake(), causing set_irq_wake_real() to return -ENXIO, and irq_set_irq_wake() to reset the wake_depth to zero. Set IRQCHIP_SKIP_SET_WAKE to indicate that irq_chip.irq_set_wake() is not implemented. Cfr. commit 10a50f1ab5f06c9a ("genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip").

2015-04-24genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chipRoger Quadros
Without this system suspend is broken on systems that have drivers calling enable/disable_irq_wake() for interrupts based off the dummy irq hook.

2012-08-21genirq: Export dummy_irq_chipKuninori Morimoto
Export dummy_irq_chip to modules to allow them to do things such as irq_set_chip_and_handler(virq, &dummy_irq_chip, handle_level_irq); This fixes ERROR: "dummy_irq_chip" [drivers/gpio/gpio-pcf857x.ko] undefined! when gpio-pcf857x.c is being built as a module.

2010-10-12genirq: Fix CONFIG_GENIRQ_NO_DEPRECATED=y buildThomas Gleixner
This option can be set to verify the full conversion to the new chip functions. Fix the fallout of the patch rework, so the core code compiles and works with it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2010-10-12genirq: Distangle kernel/irq/handle.cThomas Gleixner
kernel/irq/handle.c has become a dumpground for random code in random order. Split out the irq descriptor management and the dummy irq_chip implementation into separate files. Cleanup the include maze while at it. No code change. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Ingo Molnar <mingo@elte.hu>
