* unicore: Drop pointless includeLinus Walleij2019-07-281-1/+0
| | | | | | | | | | | I can't see why this file includes <linux/gpio.h>, it is not using any of the interfaces. Lots of things are named "gpio" in the file but it is an irqchip driver and has nothing to do with the GPIO interfaces.

* genirq: Remove irq argument from irq flow handlersThomas Gleixner2015-09-161-1/+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!

* unicore32/irq: Prepare puv3_gpio_handler for irq argument removalThomas Gleixner2015-08-011-3/+2
| | | | | | | | | | | | | The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall.

* Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt]Guan Xuetao2012-03-281-1/+0
| | | | | | | | | Disintegrate asm/system.h for Unicore32. (Compilation successful) The implementation details are not changed, but only splitted. BTW, some codestyles are adjusted. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn>
* PM / UNICORE32: Use struct syscore_ops instead of sysdevs for PMRafael J. Wysocki2011-05-111-15/+8
| | | | | | | | | | | | | Make some UNICORE32 architecture's code use struct syscore_ops objects for power management instead of sysdev classes and sysdevs. This simplifies the code and reduces the kernel's memory footprint. It also is necessary for removing sysdevs from the kernel entirely in the future. Signed-off-by: Rafael J.
