From dfc215b18aefab24e72e031029a39113508735dc Mon Sep 17 00:00:00 2001 From: Sanchayan Maity Date: Fri, 5 Aug 2016 13:59:11 +0530 Subject: usb: host: ehci-vf: Implement board_usb_phy_mode weak function Add board_usb_phy_mode weak function on similar lines to ehci-mx6. However since Vybrid USB does not have a true OTG, make this weak functon just return 0. The function is supposed to be implemented by the individual boards using a GPIO for providing the OTG pin functionality.
