| Subject | [PATCH] device-tree: nexus7: Set phy mode to otg instead of host |
| Message-ID | <rQlOO-80K-7@gated-at.bofh.it> |
In order to have the usb phy work in gadget mode, override
the default host mode with otg mode.
This allows gadget mode to work w/o any hacks to the dtsi file.

Looks like both the ifc6410 and sd600eval has OTG support on the micro-usb. Andy, how about we just change the dtsi instead? Regards, Bjorn
