2013-01-10irqchip: add basic infrastructureThomas Petazzoni
With the recent creation of the drivers/irqchip/ directory, it is desirable to move irq controller drivers here. At the moment, the only driver here is irq-bcm2835, the driver for the irq controller found in the ARM BCM2835 SoC, present in Rasberry Pi systems. This irq controller driver was exporting its initialization function and its irq handling function through a header file in <linux/irqchip/bcm2835.h>. When proposing to also move another irq controller driver in drivers/irqchip, Rob Herring raised the very valid point that moving things to drivers/irqchip was good in order to remove more stuff from arch/arm, but if it means adding gazillions of headers files in include/linux/irqchip/, it would not be very nice. So, upon the suggestion of Rob Herring and Arnd Bergmann, this commit introduces a small infrastructure that defines a central irqchip_init() function in drivers/irqchip/irqchip.c, which is meant to be called as the ->init_irq() callback of ARM platforms. This function calls of_irq_init() with an array of match strings and init functions generated from a special linker section. Note that the irq controller driver initialization function is responsible for setting the global handle_arch_irq() variable, so that ARM platforms no longer have to define the ->handle_irq field in their DT_MACHINE structure. A global header, <linux/irqchip.h> is also added to expose the single irqchip_init() function to the reset of the kernel. A further commit moves the BCM2835 irq controller driver to this new small infrastructure, therefore removing the include/linux/irqchip/ directory.

2012-09-20ARM: bcm2835: add interrupt controller driverSimon Arlott
The BCM2835 contains a custom interrupt controller, which supports 72 interrupt sources using a 2-level register scheme. The interrupt controller, or the HW block containing it, is referred to occasionally as "armctrl" in the SoC documentation, hence the symbol naming in the code. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved implementation to drivers/irchip/. * Added devicetree documentation, and hence removed list of IRQs from bcm2835.dtsi. * Changed shift in MAKE_HWIRQ() and HWIRQ_BANK() from 8 to 5 to reduce the size of the hwirq space, and pass the total size of the hwirq space to irq_domain_add_linear(), rather than just the number of valid hwirqs; the two are different due to the hwirq space being sparse. * Added the interrupt controller DT node to the top-level of the DT, rather than nesting it inside a /axi node. Hence, changed the reg value since /axi had a ranges property. This seems simpler to me, but I'm not sure if everyone will like this change or not. * Don't set struct irq_domain_ops.map = irq_domain_simple_map, hence removing the need to patch include/linux/irqdomain.h or kernel/irq/irqdomain.c. * Simplified armctrl_of_init() using of_iomap(). * Removed unused IS_VALID_BANK()/IS_VALID_IRQ() macros. * Renamed armctrl_handle_irq() to prevent possible symbol clashes. * Made armctrl_of_init() static. * Removed comment "Each bank is registered as a separate interrupt controller" since this is no longer true. * Removed FSF address from license header. * Added my name to copyright header.
