From 772ce81264b179c0e61340998e3b29e900b2fa6d Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 8 Aug 2016 21:50:51 +0900 Subject: [PATCH] usb: renesas_usbhs: Fix receiving data corrupt on R-Car Gen3 with dmac Since R-Car Gen3 SoC has the USB-DMAC, this driver should set dparam->has_usb_dmac to 1. Otherwise, behavior of this driver and the usb-dmac driver will be mismatch, then sometimes receiving data will be corrupt.
