From 8bbe61f3c10446603514aeee0aafebaaa00e8d07 Mon Sep 17 00:00:00 2001 From: Vikram Garhwal Date: Fri, 4 Dec 2020 00:52:35 +0530 Subject: usb: Add DWC3 model This patch adds skeleton model of dwc3 usb controller attached to xhci-sysbus device. It defines global register space of DWC3 controller, global registers control the AXI/AHB interfaces properties, external FIFO support and event count support. All of which are unimplemented at present,we are only supporting core reset and read of ID register. Signed-off-by: Vikram Garhwal Signed-off-by: Sai Pavan Boddu Reviewed-by: Edgar E.
