   37  - gpio-controller: if used as gpio expander.
   38  - #gpio-cells: if used as gpio expander.
   39  - interrupt-controller: if to be used as interrupt expander.
   40  - #interrupt-cells: if to be used as interrupt expander.
   41 
   42 Optional properties:
   43  - interrupts: interrupt specifier for the device's interrupt output.
   44  - reset-gpios: GPIO specification for the RESET input. This is an
   45 		active low signal to the PCA953x.
   46  - vcc-supply:	power supply regulator.
