Subject: [PATCH v6 4/5] usb: dwc3: qcom: Configure wakeup interrupts during suspend
Date: Fri, 16 Apr 2021 15:31:52 +0530
Message-ID: <1618567313-25373-5-git-send-email-sanm@codeaurora.org> (raw)
In-Reply-To: <1618567313-25373-1-git-send-email-sanm@codeaurora.org>

Configure interrupts based on hs_phy_mode to avoid triggering of
interrupts during system suspend and suspend the device successfully.
