12b13c7a88SŁukasz Stelmachdescription: |
13b13c7a88SŁukasz Stelmach  ASIX AX88796C is an Ethernet controller with a built in PHY. This
14b13c7a88SŁukasz Stelmach  describes SPI mode of the chip.
15b13c7a88SŁukasz Stelmach
16b13c7a88SŁukasz Stelmach  The node for this driver must be a child node of an SPI controller,
17b13c7a88SŁukasz Stelmach  hence all mandatory properties described in
18b13c7a88SŁukasz Stelmach  ../spi/spi-controller.yaml must be specified.
