4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx>
commit 772ce81264b179c0e61340998e3b29e900b2fa6d upstream.
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.
Fixes: de18757e272d ("usb: renesas_usbhs: add R-Car Gen3 power control")
