   6 Required properties:
   7         - compatible: "ti,tcan4x5x"
   8         - reg: 0
   9         - #address-cells: 1
  10         - #size-cells: 0
  11         - spi-max-frequency: Maximum frequency of the SPI bus the chip can
  12                              operate at should be less than or equal to 18 MHz.
  13         - interrupt-parent: the phandle to the interrupt controller which provides
  14                     the interrupt.
  15         - interrupts: interrupt specification for data-ready.

  20 Optional properties:
  21         - reset-gpios: Hardwired output GPIO. If not defined then software
  22                        reset.
  23         - device-state-gpios: Input GPIO that indicates if the device is in
  24                               a sleep state or if the device is active.
  25         - device-wake-gpios: Wake up GPIO to wake up the TCAN device.
