For gpiod conversions, if we are not willing to chase whether existing
DTSes specify polarities
properly and create workarounds in case they are wrong, we should use
gpiod_set_raw_value*()
(my preference would be to do the work and not use "raw" variants).

In this particular case, arch/arm/boot/dts/vf610-zii-dev-rev-c.dts
defines reset line as active low,
so you are leaving the device in reset state.

Please review your other conversion patches.

We also can not change the names of requested GPIOs from "reset-gpio"
to "rstn-gpios" and expect
this to work.

Stefan, please consider reverting this and applying a couple of
patches I will send out shortly.

Thanks.
