Seems that BCM2835 does not support open-drain IO, but could it be possible to
make sw emulation for it?
setup to opendrain
when output set to 1, configure as input and enable pullup (or allow pull-up
configuration).
when output set to 0, configure as output and drive low.
Allow reading input state, when output set to 0, return 0, when set to 1 return
true input value.
