[PATCH v2 10/17] tegra: usb: fdt: Add USB definitions for Tegra2 Seaboard

Simon Glass sjg at chromium.org
Sat Dec 3 13:11:33 EST 2011


We set up two USB ports, one of which can be host or device.
For some reason the kernel version does enable both ports.

Changes in v2:
- Use "okay" instead of "ok" for fdt node status
- Remove 0x from fdt aliases
