   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.

  20 See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional
  21 required property details.
  22
  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.
  31         - wakeup-source: Leave the chip running when suspended, and configure
  32                          the RX interrupt to wake up the device.
