56     is used for low power states because it disconnects the pin pull-up/down
64     pins, such as the 'bias-pull-up' property in group 2. Here is a list of
67     - drive-push-pull: Push-pull drive mode (default, not required).
68     - drive-open-drain: Open-drain drive mode.
69     - bias-disable: Disable pull-up/down (default, not required).
70     - bias-pull-up: Enable pull-up resistor.
71     - bias-pull-down: Enable pull-down resistor.
72     - slew-rate: Set the maximum speed (and so the slew-rate) of the output
75     Note that drive and bias options are mutually exclusive.
