Subject: [PATCH] at803x: fix reset handling

The driver of course "knows" that the chip's reset signal is active low,
|
|
so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however
|
|
all this will only work iff the GPIO is specified as active-high in the
|
|
device tree! I think both the driver and the device trees (if there are
|
|
any -- I was unable to find them) need to be fixed in this case...
