From bf9c85e78d0fec61360ece46dacf9ab71ba89361 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Tue, 17 Mar 2015 10:40:50 +0800 Subject: usb: chipidea: introduce ci_platform_configure It is used to configure controller parameters according to platform data, like speed, stream mode, etc, both host and device's initialization need it, most of code are the same for both roles, with this new interface, it can reduce the duplicated code and be easy to maintain in future.
