Hm, so you want the driver be still broken after changing the call to be
devm_gpiod_get_optional()? Because you can not have this driver use
gpiod API and keep parsing 'phy-reset-active-high' (by the driver
itself).
OK, I suppose I can do that...

We still parse 'phy-reset-active-high', just parsing happens elsewhere
(in gpiolib), so it is not an error to have it in a binding.
Thanks.
