Merge tag 'davinci-for-v5.1/soc-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into arm/late
DaVinci SoC updates for v5.1 (part 3) ------------------------------------- This pull request gets rid of mach-davinci private interrupt controller implmentations (aintc and cp_initc) and moves them to drivers/irqchip. mach/irqs.h usage outside of mach-davinci has been rid of. The driver changes (input and irqchip) have been acked by respective maintainers. * tag 'davinci-for-v5.1/soc-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: (57 commits) ARM: davinci: remove intc related fields from davinci_soc_info irqchip: davinci-cp-intc: move the driver to drivers/irqchip ARM: davinci: cp-intc: remove redundant comments ARM: davinci: cp-intc: drop GPL license boilerplate ARM: davinci: cp-intc: use readl/writel_relaxed() ARM: davinci: cp-intc: unify error handling ARM: davinci: cp-intc: improve coding style ARM: davinci: cp-intc: request the memory region before remapping it ARM: davinci: cp-intc: use the new-style config structure ARM: davinci: cp-intc: convert all hex numbers to lowercase ARM: davinci: cp-intc: use a common prefix for all symbols ARM: davinci: cp-intc: add the new config structures for da8xx SoCs irqchip: davinci-cp-intc: add a new config structure ARM: davinci: cp-intc: add a wrapper around cp_intc_init() ARM: davinci: cp-intc: remove cp_intc.h irqchip: davinci-aintc: move the driver to drivers/irqchip ARM: davinci: aintc: remove unnecessary includes ARM: davinci: aintc: remove the timer-specific irq_set_handler() ARM: davinci: aintc: request memory region before remapping it ARM: davinci: aintc: unify error handling ...
