Subject: lantiq: dwc2 parameters for danube
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fwigyori.git;a=commitdiff_plain;h=6f60926babe50cd1aa24fb849577fff9fe7f46b4

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.
