From 58815fa3bffdee8dbac5af6931eea991d7a71a19 Mon Sep 17 00:00:00 2001 From: Ajay Kumar Gupta Date: Thu, 25 Mar 2010 13:25:27 +0200 Subject: [PATCH] usb: musb: Add extvbus in musb_board_data EXTVBUS programming is required by OMAP3EVM REV >=E to supply 500mA power so adding a flag which can be used by musb driver to program EXTVBUS.
