  3. Subject: ar71xx: Send power to USB port on WNR2200
  4. This patch fixes ticket #15267 by enabling power on the
  5. WNR2200's USB port. At present, the USB port on the WNR2200
  6. is non-functional due to it not receiving power.
  7. This patch defines an additional GPIO pin, but none of the
  8. current GPIO definitions have been modified.
  9. Signed-off-by: Riley Baird <BM-2cVqnDuYbAU5do2DfJTrN7ZbAJ246S4XiX@bitmessage.ch>
