Yep, with the fixes-series from yesterday the bias-pull-* now have a better
default value of <1>.
so you can do
bias-pull-up;
which is then identical to the
bias-pull-up = <1>;
above (both are valid of course).
Disable would the be either
bias-disable;
or
bias-pull-up = <0>;
A driver should probably handle both, as both are valid pinconf options or
this.
