From 4037242c4f5ff77afe61bf07ca1e8a99490219e5 Mon Sep 17 00:00:00 2001 From: Ryan Mallon Date: Tue, 13 Jul 2010 05:09:16 +0100 Subject: ARM: 6209/3: at91_udc: Add vbus polarity and polling mode Allow the vbus signal to optionally use polling. This is required if the vbus signal is connected to an non-interrupting io expander for example. If vbus is in polling mode, then it is assumed that the vbus gpio may sleep. Also add an option to have vbus be an active low signal. Both options are set in the platform data for the device.
