From 21a596c17b2738fc0f13dd4cdfb6f42c397109ac Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Fri, 5 Feb 2016 13:57:11 +0900 Subject: [PATCH] usb: renesas_usbhs: Don't check CSSTS bit if peripheral mode Since Some SoCs (e.g. R-Car Gen2) don't have the CSSTS bit in the pipectrl registers ({DCP,PIPEn}CTR) because such SoCs have peripheral mode only. So, this driver should not check the CSSTS bit if peripheral mode is running.
