Vendor: Microchip Technology Inc.
Description¶
KSZ8794 ethernet switch with SPI interface
Properties¶
Top level properties¶
These property descriptions apply to “microchip,ksz8794” nodes themselves. This page also describes child node properties in the following sections.

Define the applied workaround for the switch used for
short connections. Use bitmask to select the workaround or more
0x01: Short Cable Problems with the KSZ8795 Family
0x02: 1) CAT-5E/6 Short Cable with a Link Issue for the KSZ8795 Family
0x04: 2) CAT-5E/6 Short Cable with a Link Issue for the KSZ8795 Family

|
Define the Low-Speed Interface Drive Strength for MII and RMMI
Supported values 2,4,8,12,16,20,24,28mA
see Register 163 (0xA3): Global Control 20 for more details
Legal values: |
|
|
Phandle to master port.
|
|
|
Number of slave ports on the switch
|
|
|
Set to indicate phase starts with asserted half-phase (CPHA=1).
For this driver using this property requires also using cpol.
|
|
|
Set to indicate clock leading edge is falling (CPOL=1).
For this driver using this property requires also using cpha.
|
|
|
The pin is asserted for 10ms during boot to reset the KSZ8794.
|
|
|
Maximum clock frequency of device's SPI interface in Hz
This property is required. |
|
|
GPIO specifier that controls power to the device.
This property should be provided when the device has a dedicated
switch that controls power to the device. The supply state is
entirely the responsibility of the device driver.
Contrast with vin-supply.
|
|
|
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.
This property should be provided when device power is supplied
by a shared regulator. The supply state is dependent on the
request status of all devices fed by the regulator.
Contrast with supply-gpios. If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “microchip,ksz8794” compatible.

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
