Subject: [PATCH V4 3/4] irqchip/loongson-pch-pic: Support to set IRQ type for ACPI path
Date: Thu, 20 Oct 2022 16:22:04 +0800 [thread overview]
Message-ID: <20221020082205.20505-4-lvjianmin@loongson.cn> (raw)
In-Reply-To: <20221020082205.20505-1-lvjianmin@loongson.cn>
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.
