* NXP SJA1105P 10/100/1000 Ethernet Switch Driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
### Properties of top level
|
||
|
|
- compatible: Should be "qcom,nxp,sja1105p-switch".
|
||
|
|
- reg: Should contain SPI chip select.
|
||
|
|
- spi-max-frequency: Should contain maximum spi clock frequency
|
||
|
|
for slave device.
|
||
|
|
- spi-cpha: SPI configuration to enable shift clock phase (CPHA) mode.
|
||
|
|
- switch-speed: Should contain switch ports speed 10/100/1000 Mbps.
|
||
|
|
- pinctrl-names : Names corresponding to the numbered pinctrl states
|
||
|
|
- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
|
||
|
|
- qcom,reset-gpio: Reference to the GPIO connected to the reset input.
|
||
|
|
|
||
|
|
### Properties of the port-X child node
|
||
|
|
- `null-phy`: Determines if the port has a PHY connected to it or not
|
||
|
|
- `phy-ref`: _phandle_ to the connected ethernet PHY
|
||
|
|
**NOTE**: Must be `0x00` in case there is no PHY connected to port-X
|
||
|
|
(for example if port-X is a host port or a cascaded port)
|
||
|
|
- `logical-port-num`: logical port number, used for the port mapping
|
||
|
|
**NOTE**: Must be `0xff` in case port-X is a cascaded port.
|
||
|
|
|
||
|
