From f1c9e151b18ade3be5b1865d288a490bff4339e6 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 4 Sep 2008 16:25:14 -0700 Subject: [PATCH] USB: omap_udc: sync with OMAP tree Sync up USB parts of the omap_udc support in mainline with the OMAP tree. This patch addresses some OMAP2 differences ... there's another, with respect to the double-buffering issue with PIO-IN in omap_ep_setup() (which is now out of sync with the comments), but it's not clear right now how to address that.
