6 Required properties:
7         - compatible:
8                 "ti,tcan4552", "ti,tcan4x5x"
9                 "ti,tcan4553", "ti,tcan4x5x" or
10                 "ti,tcan4x5x"
11         - reg: 0
12         - #address-cells: 1
13         - #size-cells: 0
14         - spi-max-frequency: Maximum frequency of the SPI bus the chip can
15                              operate at should be less than or equal to 18 MHz.
16         - interrupt-parent: the phandle to the interrupt controller which provides
17                     the interrupt.
18         - interrupts: interrupt specification for data-ready.

23 Optional properties:
24         - reset-gpios: Hardwired output GPIO. If not defined then software
25                        reset.
26         - device-state-gpios: Input GPIO that indicates if the device is in
27                               a sleep state or if the device is active. Not
28                               available with tcan4552/4553.
29         - device-wake-gpios: Wake up GPIO to wake up the TCAN device. Not
30                              available with tcan4552/4553.
