      1SMSC/MicroChip LAN9303 three port ethernet switch
      2-------------------------------------------------
      3
      4Required properties:
      5
      6- compatible: should be
      7  - "smsc,lan9303-i2c" for I2C managed mode
      8    or
      9  - "smsc,lan9303-mdio" for mdio managed mode
     10
     11Optional properties:
     12
     13- reset-gpios: GPIO to be used to reset the whole device
     14- reset-duration: reset duration in milliseconds, defaults to 200 ms
     15
     16Subnodes:
     17
     18The integrated switch subnode should be specified according to the binding
     19described in dsa/dsa.txt. The CPU port of this switch is always port 0.
     20
     21Note: always use 'reg = <0/1/2>;' for the three DSA ports, even if the device is
     22configured to use 1/2/3 instead. This hardware configuration will be
     23auto-detected and mapped accordingly.

     25Example:
     26
     27I2C managed mode:
     28
     29	master: masterdevice@X {
     30
     31		fixed-link { /* RMII fixed link to LAN9303 */
     32			speed = <100>;
     33			full-duplex;
     34		};
     35	};
     36
     37	switch: switch@a {
     38		compatible = "smsc,lan9303-i2c";
     39		reg = <0xa>;
     40		reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
     41		reset-duration = <200>;
     42
     43		ports {
     44			#address-cells = <1>;
     45			#size-cells = <0>;
     46
     47			port@0 { /* RMII fixed link to master */
     48				reg = <0>;
     49				label = "cpu";
     50				ethernet = <&master>;
     51			};
     52
     53			port@1 { /* external port 1 */
     54				reg = <1>;
     55				label = "lan1";
     56			};
     57
     58			port@2 { /* external port 2 */
     59				reg = <2>;
     60				label = "lan2";
     61			};
     62		};
     63	};
     64
     65MDIO managed mode:
     66
     67	master: masterdevice@X {
     68		phy-handle = <&switch>;
     69
     70		mdio {
     71			#address-cells = <1>;
     72			#size-cells = <0>;
     73
     74			switch: switch-phy@0 {
     75				compatible = "smsc,lan9303-mdio";
     76				reg = <0>;
     77				reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
     78				reset-duration = <100>;
     79
     80				ports {
     81					#address-cells = <1>;
     82					#size-cells = <0>;
     83
     84					port@0 {
     85						reg = <0>;
     86						label = "cpu";
     87						ethernet = <&master>;
     88					};
     89
     90					port@1 { /* external port 1 */
     91						reg = <1>;
     92						label = "lan1";
     93					};
     94
     95					port@2 { /* external port 2 */
     96						reg = <2>;
     97						label = "lan2";
     98					};
     99				};
    100			};
    101		};
    102	};
