Merge tag 'omap-for-v3.9/usb-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
These changes contain the OMAP USB related platform data changes that were dropped from linux next because of the merge conflicts as requested by me and Olof. The reason was that at this point we really should be able to do the arch/arm related changes separately from driver changes to avoid dependencies between branches. These patches were initially part of the USB related MFD patches. Based on our comments, Roger Quadros quickly reworked these patches into a shared branch between ARM SoC tree and the MFD tree, then separate patches for the OMAP platform data and MFD driver. Note that this branch will conflict with c1d1cd597fc7 ("ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code"). Please see http://lkml.org/lkml/2013/2/11/16 for the merge resolution. [arnd - resolved the merge conflict] Signed-off-by: Arnd Bergmann <arnd@arndb.de>
