In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier.

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!

2015-07-16irqchip/tb10x: Prepare tb10x_irq_cascade for irq argument removalThomas Gleixner1-1/+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. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Julia Lawall <Julia.Lawall@lip6.fr>
2015-07-11irqchip/tb10x: Consolidate chained IRQ handler install/removeThomas Gleixner1-2/+2
Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Search and conversion was done with coccinelle: @@ expression E1, E2, E3; @@ ( -if (irq_set_handler_data(E1, E2) != 0) - BUG(); | -irq_set_handler_data(E1, E2); ) -irq_set_chained_handler(E1, E3); +irq_set_chained_handler_and_data(E1, E3, E2); @@ expression E1, E2, E3; @@ ( -if (irq_set_handler_data(E1, E2) != 0) - BUG(); ... | -irq_set_handler_data(E1, E2); ... ) -irq_set_chained_handler(E1, E3); +irq_set_chained_handler_and_data(E1, E3, E2); Reported-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Jason Cooper <jason@lakedaemon.net>
2015-07-11irqchip: Prepare for local stub header removalJoel Porquet1-1/+1
The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so the local irqchip.h became an empty shell, which solely includes include/linux/irqchip.h Include the global header in all irqchip drivers instead of the local header, so we can remove it.

2014-11-09genirq: Generic chip: Change irq_reg_{readl,writel} argumentsKevin Cernekee1-2/+2
Pass in the irq_chip_generic struct so we can use different readl/writel settings for each irqchip driver, when appropriate. Compute (gc->reg_base + reg_offset) in the helper function because this is pretty much what all callers want to do anyway. Compile-tested using the following configurations: at91_dt_defconfig (CONFIG_ATMEL_AIC_IRQ=y) sama5_defconfig (CONFIG_ATMEL_AIC5_IRQ=y) sunxi_defconfig (CONFIG_ARCH_SUNXI=y) tb10x (ARC) is untested.
