Subject: [PATCH V1 1/1] soc: qcom: smp2p: Add wakeup capability to SMP2P IRQ
Date: Thu, 5 Aug 2021 21:47:33 +0530 [thread overview]
Message-ID: <1628180254-758-1-git-send-email-deesin@codeaurora.org> (raw)
Some use cases require SMP2P interrupts to wake up the host
from suspend. Mark smp2p interrupt as wakeup capable to abort
the suspend.
