Subject: [PATCH 4.9 31/32] usb: dwc3: dont set gadget->is_otg flag
Date: Sat, 11 Apr 2020 14:09:10 +0200 [thread overview]
Message-ID: <20200411115422.811567810@linuxfoundation.org> (raw)
In-Reply-To: <20200411115418.455500023@linuxfoundation.org>
From: Roger Quadros <rogerq@ti.com>
commit c09b73cfac2a9317f1104169045c519c6021aa1d upstream.
This reverts
commit 6a4290cc28be1 ("usb: dwc3: gadget: set the OTG flag in dwc3 gadget driver.")
We don't yet support any of the OTG mechanisms (HNP/SRP/ADP)
and are not setting gadget->otg_caps, so don't set gadget->is_otg
flag.
If we do then we end up publishing a OTG1.0 descriptor in
the gadget descriptor which causes device enumeration to fail
if we are connected to a host with CONFIG_USB_OTG enabled.
