linux/arch/arm/mach-omap2/usb-host.c
Arnd Bergmann 6e7f7cfce2 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 c1d1cd597f
 ("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.
