From cd0b42c2a6d2a74244f0053f8960f5dad5842278 Mon Sep 17 00:00:00 2001 From: Chris Ruehl Date: Fri, 10 Jan 2014 13:51:30 +0800 Subject: [PATCH] usb: chipidea: put hw_phymode_configure before ci_usb_phy_init hw_phymode_configure configures the PORTSC registers and allow the following phy_inits to operate on the right parameters. This fix a problem where the UPLI (ISP1504) could not be detected, because the Viewport was not available and read the viewport return 0's only.
