+Vitesse VSC73xx Switches
+========================
+
+This defines device tree bindings for the Vitesse VSC73xx switch chips.
+The Vitesse company has been acquired by Microsemi and Microsemi in turn
+acquired by Microchip but retains this vendor branding.
+
+The currently supported switch chips are:
+Vitesse VSC7385 SparX-G5 5+1-port Integrated Gigabit Ethernet Switch
+Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch
+Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch
+Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch
+
+The device tree node is an SPI device so it must reside inside a SPI bus
+device tree node, see spi/spi-bus.txt
+
+Required properties:
+
+- compatible: must be exactly one of:
+ "vitesse,vsc7385"
+ "vitesse,vsc7388"
+ "vitesse,vsc7395"
+ "vitesse,vsc7398"
+- gpio-controller: indicates that this switch is also a GPIO controller,
+ see gpio/gpio.txt
+- #gpio-cells: this must be set to <2> and indicates that we are a twocell
+ GPIO controller, see gpio/gpio.txt
+
+Optional properties:
+
+- reset-gpios: a handle to a GPIO line that can issue reset of the chip.
+ It should be tagged as active low.
+
+Required subnodes:
+
+See net/dsa/dsa.txt for a list of additional required and optional properties
+and subnodes of DSA switches.
+
+Examples:
+
+switch@0 {
+ compatible = "vitesse,vsc7395";
+ reg = <0>;
+ /* Specified for 2.5 MHz or below */
+ spi-max-frequency = <2500000>;
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ label = "lan1";
+ };
+ port@1 {
+ reg = <1>;
+ label = "lan2";
+ };
+ port@2 {
+ reg = <2>;
+ label = "lan3";
+ };
+ port@3 {
+ reg = <3>;
+ label = "lan4";
+ };
+ vsc: port@6 {
+ reg = <6>;
+ label = "cpu";
+ ethernet = <&gmac1>;
+ phy-mode = "rgmii";
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ pause;
+ };
+ };
+ };
+};
