From 40dcd0e8067b35e247f74409d79443634daf35ac Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Thu, 13 Jun 2013 17:59:56 +0300 Subject: usb: chipidea: add PTW, PTS and STS handling This patch makes it possible to configure the PTW, PTS and STS bits inside the portsc register for host and device mode before the driver starts and the phy can be addressed as hardware implementation is designed.
