Subject: [PATCH v13 07/12] usb: ehci: use bus->sysdev for DMA configuration
Date: Sat, 11 Feb 2017 09:27:18 +0800 [thread overview]
Message-ID: <1486776443-2280-8-git-send-email-peter.chen@nxp.com> (raw)
In-Reply-To: <1486776443-2280-1-git-send-email-peter.chen@nxp.com>
Set the dma for ehci from sysdev. The sysdev is pointing to device that
is known to the system firmware or hardware.
