-Subject: [PATCH 177/224] phy: phy-mtk-tphy: use auto instead of force to
- bypass utmi signals
-
-When system is running, if usb2 phy is forced to bypass utmi signals,
-all PLL will be turned off, and it can't detect device connection
-anymore, so replace force mode with auto mode which can bypass utmi
-signals automatically if no device attached for normal flow.
-But keep the force mode to fix RX sensitivity degradation issue.
