The final value in this interrupts property means IRQ_TYPE_NONE.
A WARN_ON() was added early this year to complain about use of
IRQ_TYPE_NONE: 83a86fbb5b56 "irqchip/gic: Loudly complain about
the use of IRQ_TYPE_NONE", resulting in many warnings spewing
forth when I boot an APQ8074 Dragonboard. I am trying to
determine whether the warning is overly aggressive, or whether
the IRQ TYPE is incorrectly specified for the spmi node.
The interrupt-parent for the spmi node is intc: interrupt-controller@f9000000,
which has compatible = "qcom,msm-qgic2". I do not know the architecture
or implementation of this interrupt controller. Is an IRQ_TYPE_NONE
valid in this case, or should a specific type be provided?
Thanks!
