From b4a83e4df1bc864e89d3bb90e97f9caab656545d Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Fri, 25 Jan 2013 08:03:21 +0530 Subject: usb: otg: add an api to bind the usb controller and phy In order to support platforms which has multiple PHY's (of same type) and which has multiple USB controllers, a new design is adopted wherin the binding information (between the PHY and the USB controller) should be passed to the PHY library from platform specific file (board file). So added a new API to pass the binding information.
