From: Thinh Nguyen Thinh.Nguyen@synopsys.com Date: Fri, 2 Feb 2018 13:21:35 -0800 Subject: usb: dwc3: Fix GDBGFIFOSPACE_TYPE values
From: Thinh Nguyen Thinh.Nguyen@synopsys.com
commit b16ea8b9492e99e03b1269fe93ebdbf8e4eabf8a upstream.
The FIFO/Queue type values are incorrect. Correct them according to DWC_usb3 programming guide section 1.2.27 (or DWC_usb31 section 1.2.25).
Additionally, this patch includes ProtocolStatusQ and AuxEventQ types.
