1 * NXP PCA953x I2C GPIO multiplexer
4 - compatible: Has to contain one of the following:
38 - gpio-controller: if used as gpio expander.
39 - #gpio-cells: if used as gpio expander.
40 - interrupt-controller: if to be used as interrupt expander.
41 - #interrupt-cells: if to be used as interrupt expander.
44 - interrupts: interrupt specifier for the device's interrupt output.
45 - reset-gpios: GPIO specification for the RESET input. This is an
46 active low signal to the PCA953x.
47 - vcc-supply: power supply regulator.
