> This series brings in the kernel fdt file and provides a working > USB driver for Tegra2 Seaboard. > > (I have done this in one series since otherwise most of the fdt additions > will just look like dead code.) > > The driver requires CONFIG_OF_CONTROL and a device tree to operate. > > Some enhancements to fdtdec are required to make this easier, and these > are included in the series also.
