From 404b183aa892cb00ea215068a41b56603b22a95a Mon Sep 17 00:00:00 2001 From: John Crispin Date: Mon, 14 Sep 2015 20:08:15 +0000 Subject: [PATCH] lantiq: Add AR9 compatibility bits to DWC2 driver MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add AR9 DTS definition to be recognized by the DWC2 driver. The same driver parameters can be mostly used except that some boards seem to erroneously report OTG HNP/SRP capability of the USB HCD. Forcing the HNP/SRP off allows these boards to work with the DWC2 as well.
