   12 description: |
   13   ASIX AX88796C is an Ethernet controller with a built in PHY. This
   14   describes SPI mode of the chip.
   15 
   16   The node for this driver must be a child node of an SPI controller,
   17   hence all mandatory properties described in
   18   ../spi/spi-controller.yaml must be specified.
