- Subject: ar71xx: Send power to USB port on WNR2200
- This patch fixes ticket #15267 by enabling power on the
- WNR2200's USB port. At present, the USB port on the WNR2200
- is non-functional due to it not receiving power.
- This patch defines an additional GPIO pin, but none of the
- current GPIO definitions have been modified.

- Backport of r47236
