Subject: [PATCH] Changes since v1 - Change subject form "ALSA" to "USB:" - Adjust to approoriate line
Date: Wed, 18 Nov 2020 14:51:32 +0800 [thread overview]
Message-ID: <20201118065132.24772-1-penghao@uniontech.com> (raw)
USB: quirks: Add USB_QUIRK_DISCONNECT_SUSPEND quirk for
Lenovo A630Z TIO built-in usb-audio card
Add a USB_QUIRK_DISCONNECT_SUSPEND quirk for the Lenovo TIO built-in
usb-audio. when A630Z going into S3,the system immediately wakeup 7-8
seconds later by usb-audio disconnect interrupt to avoids the issue.
Seeking a better fix, we've tried a lot of things, including:
- Check that the device's power/wakeup is disabled
- Check that remote wakeup is off at the USB level
- All the quirks in drivers/usb/core/quirks.c
e.g. USB_QUIRK_RESET_RESUME,
USB_QUIRK_RESET,
USB_QUIRK_IGNORE_REMOTE_WAKEUP,
USB_QUIRK_NO_LPM.
but none of that makes any difference.
There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.
Introduce a quirk to disable the port during suspend when the modem is
detected.
