Subject: [PATCH V3 4/4] irqchip/loongson-liointc: Support to set irq type for ACPI path
Date: Sun, 9 Oct 2022 14:44:31 +0800 [thread overview]
Message-ID: <20221009064431.18839-5-lvjianmin@loongson.cn> (raw)
In-Reply-To: <20221009064431.18839-1-lvjianmin@loongson.cn>
For ACPI path, the xlate callback used IRQ_TYPE_NONE and ignored
the irq type in intspec[1]. For supporting to set type for
irqs of the irqdomain, intspec[1] should be used to get irq
type.
