Merge tag 'intc-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
Merge "omap intc changes for v3.18 merge window" from Tony Lindgren: Interrupt code related clean-up for omap2 and 3 to make it ready to move to drivers/irqchip. Note that this series does not yet move the interrupt code to drivers, that will be posted separately as a follow-up series. Note that this branch has a dependency to patches both in fixes-v3.18-not-urgent and soc-for-v3.18 and is based on a merge. Without doing the merge, off-idle would not work properly for git bisect. * tag 'intc-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (325 commits) arm: omap: intc: switch over to linear irq domain arm: omap: irq: get rid of ifdef hack arm: omap: irq: introduce omap_nr_pending arm: omap: irq: remove nr_irqs argument arm: omap: irq: remove unnecessary header arm: omap: irq: drop omap2_intc_handle_irq() arm: omap: irq: drop omap3_intc_handle_irq() arm: omap: irq: call set_handle_irq() from .init_irq arm: omap: irq: move some more code around arm: boot: dts: omap2/3/am33xx: drop ti,intc-size arm: omap: irq: drop ti,intc-size support arm: boot: dts: am33xx/omap3: fix intc compatible flag arm: omap: irq: use compatible flag to figure out number of IRQ lines arm: omap: irq: add specific compatibles for omap3 and am33xx devices arm: omap: irq: drop .handle_irq and .init_irq fields arm: omap: irq: use IRQCHIP_DECLARE macro arm: omap: irq: call set_handle_irq() from intc_of_init arm: omap: irq: make intc_of_init static arm: omap: irq: reorganize code a little bit arm: omap: irq: always define omap3 support ...
