From f3482a4e400b3123244cc2bd97c0bb52d1005359 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Wed, 11 Mar 2015 17:08:15 +0000 Subject: [PATCH] lantiq: Add sensible hw-defaults for dwc2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Lantiq driver does not work with autodetected fifo sizes so use ones from original ltq-hcd driver in dwc2. Other values can be autodetected.
