Subject: [PATCH V13 13/13] LoongArch: Fix irq number for timer and ipi
Date: Mon, 27 Jun 2022 19:39:57 +0800	[thread overview]
Message-ID: <1656329997-20524-14-git-send-email-lvjianmin@loongson.cn> (raw)
In-Reply-To: <1656329997-20524-1-git-send-email-lvjianmin@loongson.cn>

After supporting LoongArch CPUINTC controller driver, the
irq number of interrupt source from CPUINTC is needed to transfer
from CPUINTC irqdomain, so use api of CPUINTC to transfer it.
