Subject: [PATCH 2/2] usb: dwc3: gadget: Clean up DCFG/DSTS FULLSPEED macro
Date: Tue, 29 Nov 2016 12:56:37 +0200	[thread overview]
Message-ID: <1480416997-19757-3-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1480416997-19757-1-git-send-email-rogerq@ti.com>

DCFG/DSTS.FULLSPEED can be either 0x1 or 0x3.
Let's call 0x1 as DCFG/DSTS_FULLSPEED1 and 0x3 as DCFG/DSTS_FULLSPEED3.
