Vendor: Microchip Technology Inc.

Description

KSZ8863 ethernet switch

Properties

Top level properties

These property descriptions apply to “microchip,ksz8863” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

Name

Type

Details

dsa-master-port

phandle

Phandle to master port.

dsa-slave-ports

int

Number of slave ports on the switch

spi-cpha

boolean

Set to indicate phase starts with asserted half-phase (CPHA=1).
For this driver using this property requires also using cpol.

spi-cpol

boolean

Set to indicate clock leading edge is falling (CPOL=1).
For this driver using this property requires also using cpha.

reset-gpios

phandle-array

The pin is asserted for 10ms during boot to reset the KSZ8794.

spi-max-frequency

int

Maximum clock frequency of device's SPI interface in Hz

This property is required.

supply-gpios

phandle-array

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.

vin-supply

phandle

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.
