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.
