I don't know, I think it's fine. It's certainly this way in the kernel. And for all I know, this GPIO does actually affect VBUS as well as flipping any mux (and the more I think about that, the more likely it is) although I can't actually know for sure since I don't have the schematics. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
