Are you looking for a kernel for a specific embedded board? If so, you should contact your vendor for that support. If you're looking for support for the Synopsis Design Ware 3 device/host controller, the device controller support was added by Felipe Balbi, and he can tell you which kernel version is best to use. He will probably tell you the latest kernel, 3.3, that is about to be released. DW3 host side support will apparently be added by these patches in 3.4, if I can get them merged this week.
