From bb59dbff4e5fb0ac14e3ee47d3f688490f128155 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Thu, 7 Jul 2011 09:58:43 +0900 Subject: usb: gadget: m66592-udc: add function for external controller M66592 has the pin of WR0 and WR1. So, if one write-pin of CPU connects to the pins, we have to change the setting of FIFOSEL register in the controller. If we don't change the setting, the controller cannot send the data of odd length.
