Subject: [PATCH 1/2] usb: dwc3: gadget: Set gadget_max_speed when set ssp_rate
Date: Mon, 08 Mar 2021 18:16:44 -0800 [thread overview]
Message-ID: <0b2732e2f380d9912ee87f39dc82c2139223bad9.1615254129.git.Thinh.Nguyen@synopsys.com> (raw)
In-Reply-To: <cover.1615254129.git.Thinh.Nguyen@synopsys.com>
Set the dwc->gadget_max_speed to SuperSpeed Plus if the user sets the
ssp_rate. The udc_set_ssp_rate() is intended for setting the gadget's
speed to SuperSpeed Plus at the specified rate.
