Subject: [PATCH] usb: dwc3: Set DWC3 context's mode based on selected mode.
Date: Sat, 02 Mar 2013 18:55:24 +0530 [thread overview]
Message-ID: <1362230724-21017-1-git-send-email-gautam.vivek@samsung.com> (raw)
In-Reply-To: <CAFp+6iGGAY=nMg03-bqHz=XuNP+1t9mQR=M53HGoqCXv=t+f0Q@mail.gmail.com>
Now that machines may select the mode of working of DWC3 (HOST only,
GADGET only or DUAL_ROLE), lets set DWC3 mode based on that
rather than fixing it to whatever DWC3 hardware says.
This way we can skip initializing Gadget/Host in case
we are using Host-only/Gadget-only mode respectively.
