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.
