Subject: [PATCH] ARC: [plat-hsdk]: Add reset controller handle to manage USB reset
Date:   Fri, 15 Feb 2019 19:17:33 +0300

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

DW USB controller on HSDK hangs sometimes after SW reset, so
add reset handle to make possible to reset DW USB controller HW.
