From 6f60926babe50cd1aa24fb849577fff9fe7f46b4 Mon Sep 17 00:00:00 2001 From: Ben Mulvihill Date: Tue, 8 Nov 2016 22:03:14 +0100 Subject: [PATCH] lantiq: dwc2 parameters for danube Parameters for dwc2 on lantiq. A separate dwc2_core_params structure is defined for danube because danube fifo sizes are large enough to be autodetected. This is not the case on arx and vrx.
