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.

A GPIO line handling reset of the chip. As the line is active low,
it should be marked GPIO_ACTIVE_LOW.
