Subject: [PATCH v13 4/6] usb: dwc3: qcom: Configure wakeup interrupts during suspend
Date: Tue, 12 Apr 2022 00:46:52 +0530	[thread overview]
Message-ID: <1649704614-31518-5-git-send-email-quic_c_sanm@quicinc.com> (raw)
In-Reply-To: <1649704614-31518-1-git-send-email-quic_c_sanm@quicinc.com>

Configure DP/DM interrupts to detect line state changes based on
hs_phy_mode. Enable the triggers opposite of what the current
DP, DM levels. For HS/FS mode enable DM interrupt and for LS enable DP
interrupt.
