If port terminations are detected in suspend, but link never reaches U0 then xHCI may have an internal uncleared wake state that will cause an immediate wake after suspend. This wake state is normally cleared when driver clears the PORT_CSC bit, which is set after a device is enabled and in U0. Write 1 to clear PORT_CSC for ports that don't have anything connected when suspending. This makes sure any pending internal wake states in xHCI are cleared.
