Subject: irqchip/loongson-pch-pic: Support to set IRQ type for ACPI path
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=25f3514aab3748bfef4a279ed599f836ac83e62a;p=linux.git

irqchip/loongson-pch-pic: Support to set IRQ type for ACPI path

For ACPI path, the translate callback used IRQ_TYPE_NONE and ignored
the IRQ type in fwspec->param[1]. For supporting to set type for
IRQs of the irqdomain, fwspec->param[1] should be used to get IRQ
type.
