Revision bbfbf04c2d4ef673f657175456f6693c9225748a authored by Masahiro Yamada on 14 June 2018, 05:27:45 UTC, committed by Linus Walleij on 23 July 2018, 21:13:31 UTC
If a GPIO chip is a part of a hierarchy IRQ domain, there is no way to specify the trigger type when gpio(d)_to_irq() allocates an interrupt on-the-fly. Currently, uniphier_gpio_to_irq() sets IRQ_TYPE_NONE, but it causes an error in the .alloc() hook of the parent domain. (drivers/irq/irq-uniphier-aidet.c) Even if we change irq-uniphier-aidet.c to accept the NONE type, GIC complains about it since commit 83a86fbb5b56 ("irqchip/gic: Loudly complain about the use of IRQ_TYPE_NONE"). Instead, use IRQ_TYPE_LEVEL_HIGH as a temporary value when an irq is allocated. irq_set_irq_type() will override it when the irq is really requested.
