Some Type-C multi-port adapters which do not support usb connection are advertising the multi-functionality in DP alt mode. If multi-functionality is preferred, the DP driver assumes the adapter supports usb connection and USB phy driver will program the PHY mode to DP+USB. In source mode, usb PD driver checks for the peer_usb_connection of the adapter. If it does not support usb then it will stop usb stack and update the PHY MODE to USB only mode from phy_suspend path. The result is, usb may program the combo PHY to usb only mode when DP is already connected. This is causing AUX read/write timeouts when DP is trying to access the phy registers. To fix this issue, a flag in SVID connect handler in usbpd driver to notify peer_usb_comm support to the DP driver. DP driver will read this flag and program the phy mode.
