1 Vitesse VSC73xx Switches
2 ========================
4 This defines device tree bindings for the Vitesse VSC73xx switch chips.
5 The Vitesse company has been acquired by Microsemi and Microsemi in turn
6 acquired by Microchip but retains this vendor branding.
8 The currently supported switch chips are:
9 Vitesse VSC7385 SparX-G5 5+1-port Integrated Gigabit Ethernet Switch
10 Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch
11 Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch
12 Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch
14 The device tree node is an SPI device so it must reside inside a SPI bus
15 device tree node, see spi/spi-bus.txt
19 - compatible: must be exactly one of:
24 - gpio-controller: indicates that this switch is also a GPIO controller,
26 - #gpio-cells: this must be set to <2> and indicates that we are a twocell
27 GPIO controller, see gpio/gpio.txt
31 - reset-gpios: a handle to a GPIO line that can issue reset of the chip.
32 It should be tagged as active low.
36 See net/dsa/dsa.txt for a list of additional required and optional properties
37 and subnodes of DSA switches.
