From 6c27f939b885c00924c745735739ba6d54eae6f0 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Fri, 27 Sep 2013 11:53:28 +0530 Subject: arm: omap3: twl: add phy consumer data in twl4030_usb_data The PHY framework uses the phy consumer data populated in platform data in the case of non-dt boot to return the reference to the PHY when the controller (PHY consumer) requests for it. So populated the phy consumer data in the platform data of twl usb.
