With  the 'phylib' now  being aware of  the "reset-gpios" PHY node property,
there should be no need to frob the PHY reset in this  driver anymore...

Hi Sergei

The code you are deleting would of ignored the flags in the gpio

I don't parse this.

The code deleted does take the flag into account.

Not really -- you need to call of_get_named_gpio_flags() (with a valid last argument) for that.

And the DT property
associated to it seems correct to me (I mean, with proper flag
specification).

It apparently is not as it have GPIO_ACTIVE_HIGH and the driver assumes active-low reset signal.

[...]
Bye,

MBR, Sergei
