Subject: [v15 5/6] usb: dwc3: qcom: Configure wakeup interrupts during suspend
Date: Thu, 5 May 2022 14:26:12 +0530 [thread overview]
Message-ID: <1651740973-7944-6-git-send-email-quic_kriskura@quicinc.com> (raw)

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.
