    +description: |
    + ASIX AX88796C is an Ethernet controller with a built in PHY. This
    + describes SPI mode of the chip.
    +
    + The node for this driver must be a child node of an SPI controller,
    + hence all mandatory properties described in
    + ../spi/spi-controller.yaml must be specified.
