* irq: openrisc: perform irqentry in entry codeMark Rutland2021-10-261-5/+0
| | | | | | | | | | | | | | | | In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have arch/openrisc perform all the irqentry accounting in its entry code. As arch/openrisc uses GENERIC_IRQ_MULTI_HANDLER, we can use generic_handle_arch_irq() to do so. There should be no functional change as a result of this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that openrisc copied arm64's GENERIC_IRQ_MULTI_HANDLER code (which came from arm). Cnvert it to use the generic version.

* irqchip: or1k-pic: Migrate from arch/openrisc/Stefan Kristiansson2014-07-011-133/+13
| | | | | | | | | | | | | | | | | | | | | In addition to consolidating the or1k-pic with other interrupt controllers, this makes OpenRISC less tied to its on-cpu interrupt controller. All or1k-pic specific parts are moved out of irq.c and into drivers/irqchip/irq-or1k-pic.c In that transition, the functionality have been divided into three chip variants. One that handles level triggered interrupts, one that handles edge triggered interrupts and one that handles the interrupt controller that is present in the or1200 OpenRISC cpu implementation.
