Attached is my musb patch updated with you tree. The other version without the board files is already going to mailine -rc3 merge via Greg's queue.

>From 36f142f092683d64b4e025a836c32290bc641d57 Mon Sep 17 00:00:00 2001 From: Felipe Balbi <felipe.balbi@xxxxxxxxx> Date: Thu, 14 Aug 2008 14:41:26 +0300 Subject: [PATCH] usb: musb: pass configuration specifics via pdata Use platform_data to pass musb configuration-specific details to musb driver. This patch will prevent that other platforms selecting HAVE_CLK and enabling musb won't break tree building. The other parts of it will come when linux-omap merge up more omap2/3 board-files.
