+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.

+      it should be marked GPIO_ACTIVE_LOW.
