Hi,

I like the option #1 as well. The generic driver should rely and parse
existing bindings like 'reset-gpios'. Still additional property (e.g.
"do-the-power-sequence") seems needed as we do not want to play with all
reset-gpios in DTB.

Great, that sounds good! I'll start the work.

Best regards,
Krzysztof
