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 at 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?

No, IRQ_TYPE_NONE isn't valid and the WARN_ON() is reasonable.

Please change it to IRQ_TYPE_LEVEL_HIGH. And while you're at it, replace
the first 0 with GIC_SPI.


If you have more of these warnings you can most likely look at e.g.
msm8916 (arm64) to find the right flags.
