This patch enables UMS on the nyan devices like the nyan-big. A patch like this has been sent in by Stephen Warren some time ago for other tegra devices: commit e6607cffef965011ef0ddc0fbe6f4b7c0d53aeec But the nyan devices never received that functionality.

That should be below the ---, but I assume Tom can fix that when applying the patch.

Do you also need to add aliases for the USB nodes, like I did in my similar patch:

At least for nyan-big this is done in the: tegra124-nyan-big.dts file. So there is no need to also do this here.
