The series can be logically split into four parts. The first (1-8) aims at introducing support for SPARSE_IRQ. It contains a couple changes required for that functionality and the final patch actually selecting it. Second part (9-19) makes the aintc driver suitable for drivers/irqchip and eventually moves it over there. Part 3 (20-32) does the same for the cp-intc driver. Last patch removes unnecessary code. The series has been tested on da850-lcdk (for cp-intc) and dm365-evm (for aintc). v1 -> v2: - made commit messages readable without reading the subject line first - collected David's Reviewed-by tags for patches that haven been significantly modified since v1 - added handling of spurious interrupts in cp-intc - added comments explaining the irq handlers (C versions translated from assembly) - dropped the patches removing the hardware interrupt numbers from the priority tables - don't remove irqs.h, make it a local header instead - rearranged the patches in order not to remove the code added by earlier ones - renamed d*_init_irqs to d*_init_irq to fit the name of the relevant callback in machine info struct - fixed license identifiers where needed - added comments to config structures for irqchip drivers - fixed all off-by-one errors in resource sizes - clarified the comments on the weird handling of IRQ_TINT1_TINT34 as level irq and added missing calls to irq_set_handler() to dm3* SoCs - fixed one function that was missing a correct prefix in cp_intc - return value variables should be called ret not rv - added a patch converting calls to _raw_readl/writel() to their _relaxed counterparts - fixed the commit message prefix in patches that belong to the irqchip subsystem - other minor tweaks Bartosz Golaszewski (33): ARM: davinci: remove intc_host_map from davinci_soc_info struct ARM: davinci: aintc: use irq domain ARM: davinci: select GENERIC_IRQ_MULTI_HANDLER ARM: davinci: remove davinci_intc_type ARM: davinci: pull davinci_intc_base into the respective intc drivers ARM: davinci: wrap HW interrupt numbers with a macro ARM: davinci: select SPARSE_IRQ ARM: davinci: make irqs.h a local header ARM: davinci: aintc: drop GPL license boilerplate ARM: davinci: aintc: wrap davinci_irq_init() with a helper ARM: davinci: aintc: use a common prefix for symbols in the driver ARM: davinci: aintc: drop the 00 prefix from register offsets ARM: davinci: aintc: use readl/writel_relaxed() irqchip: davinci-aintc: add a new config structure ARM: davinci: aintc: use the new irqchip config structure in dm* SoCs ARM: davinci: aintc: use the new config structure ARM: davinci: aintc: move timer-specific irq_set_handler() out of irq.c ARM: davinci: aintc: remove unnecessary includes irqchip: davinci-aintc: move the driver to drivers/irqchip ARM: davinci: cp-intc: remove cp_intc.h ARM: davinci: cp-intc: add a wrapper around cp_intc_init() irqchip: davinci-cp-intc: add a new config structure ARM: davinci: cp-intc: add the new config structures for da8xx SoCs ARM: davinci: cp-intc: use a common prefix for all symbols ARM: davinci: cp-intc: convert all hex numbers to lowercase ARM: davinci: cp-intc: use the new-style config structure ARM: davinci: cp-intc: improve coding style ARM: davinci: cp-intc: unify error handling ARM: davinci: cp-intc: use readl/writel_relaxed() ARM: davinci: cp-intc: drop GPL license boilerplate ARM: davinci: cp-intc: remove redundant comments irqchip: davinci-cp-intc: move the driver to drivers/irqchip ARM: davinci: remove intc related fields from davinci_soc_info arch/arm/Kconfig | 2 + arch/arm/mach-davinci/Kconfig | 19 +- arch/arm/mach-davinci/Makefile | 3 -
