Hi Antoniu,

thanks for your patch!

So tying into the binding discussion:

GPIO means "general purpose input/output".

I am really confused as whether this is:

- General purpose - seems to be for the purpose of switching
  currents and nothing else.

- Input/Output - It's switching something else and not inputting
  or outputting anything and this makes the driver look strange.

Yours,
