From 18e69a35efbb078403db0c0063986470dad7d082 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Fri, 14 Mar 2008 23:20:18 +0300 Subject: 83xx/fdt_support: let user specifiy FSL USB Dual-Role controller role Linux understands "host" (default), "peripheral" and "otg" (broken). Though, U-Boot doesn't restrict dr_mode variable to these values (think of renames in future).
