Date: Sat, 22 Oct 2022 15:59:54 +0800 From: Jianmin Lv <lvjianmin@...ngson.cn> To: Thomas Gleixner <tglx@...utronix.de>, Marc Zyngier <maz@...nel.org> Cc: linux-kernel@...r.kernel.org, loongarch@...ts.linux.dev, Jiaxun Yang <jiaxun.yang@...goat.com>, Huacai Chen <chenhuacai@...ngson.cn>, Bjorn Helgaas <bhelgaas@...gle.com>, Len Brown <lenb@...nel.org>, rafael@...nel.org, linux-pci@...r.kernel.org, linux-acpi@...r.kernel.org Subject: [PATCH V5 3/4] 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.
