From fa4a8d722bc2f0b1887ea929874a0f6754eda8b4 Mon Sep 17 00:00:00 2001 From: Mian Yousaf Kaukab Date: Fri, 30 Jan 2015 09:09:35 +0100 Subject: [PATCH] usb: dwc2: gadget: fix phy interface configuration hsotg->phyif is set in dwc2_gadget_init according to phy interface width. Use it for configuration instead of hardcoded value. Moreover, set USB turnaround time according to phy width.
