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.
