Hi Greg,

Today's linux-next merge of the usb tree got a conflict in
arch/arm/mach-mx2/devices.c between various commits from the i.MX tree
and commits 304ae32ac8ac68ac5a091a67187645dc84b6067c ("USB: MXC: use
DMA_BIT_MASK macro rather than hardcoded constants") and
3f1c5d0f4c64f5e9e4ac329a935b3da67593691f ("USB: MXC: add platform
resources for i.MX21 USB host controller") from the usb tree.

I fixed it up (I think - see below) and cam carry the fixes as necessary.
