1 * PCF857x-compatible I/O expanders
3 The PCF857x-compatible chips have "quasi-bidirectional" I/O lines that can be
4 driven high by a pull-up current source or driven low to ground. This combines
14   - compatible: should be one of the following.

29   - reg: I2C slave address.
31   - gpio-controller: Marks the device node as a gpio controller.
32   - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
33     cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the

50   - interrupt-controller: Identifies the node as an interrupt controller.
