From 94adcdce0d340e06eb9187cad70555d2e8a201f3 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Wed, 28 May 2014 20:22:58 +0900 Subject: [PATCH] usb: host: xhci-plat: add xhci_plat_start() Some platforms (such as the Renesas R-Car) need to initialize some specific registers after xhci driver calls usb_add_hcd() and before the driver calls xhci_run(). So, this patch adds the xhci_plat_start() function.
