1 Realtek SMI-based Switches
4 The SMI "Simple Management Interface" is a two-wire protocol using
5 bit-banged GPIO that while it reuses the MDIO lines MCK and MDIO does
6 not use the MDIO protocol. This binding defines how to specify the
7 SMI-based Realtek devices.
11 - compatible: must be exactly one of:
23 - mdc-gpios: GPIO line for the MDC clock line.
24 - mdio-gpios: GPIO line for the MDIO data line.
25 - reset-gpios: GPIO line for the reset signal.
28 - realtek,disable-leds: if the LED drivers are not used in the
34 - interrupt-controller
38 interrupt line coming out of one of the SMI-based chips. It most
42 Required properties of interrupt-controller:
44 - interrupt: parent interrupt, see interrupt-controller/interrupts.txt
45 - interrupt-controller: see interrupt-controller/interrupts.txt
46 - #address-cells: should be <0>
47 - #interrupt-cells: should be <1>
49 - mdio
51 This defines the internal MDIO bus of the SMI device, mostly for the
55 Required properties of mdio:
57 - compatible: should be set to "realtek,smi-mdio" for all SMI devices
59 See net/mdio.txt for additional MDIO bus properties.
