Subject: [PATCH V1 4/4] irqchip/loongson-liointc: Add IRQCHIP_SKIP_SET_WAKE flag
Date: Sat, 20 May 2023 14:38:18 +0800 [thread overview]
Message-ID: <20230520063818.27208-5-lvjianmin@loongson.cn> (raw)
In-Reply-To: <20230520063818.27208-1-lvjianmin@loongson.cn>
From: Yinbo Zhu <zhuyinbo@loongson.cn>
Liointc doesn't require specific logic to work with wakeup IRQs,
and no irq_set_wake callback is needed. To allow registered IRQs
from liointc to be used as a wakeup-source, and ensure irq_set_irq_wake()
works well, the flag IRQCHIP_SKIP_SET_WAKE should be added.
