+Xilinx TSN (time sensitive networking) Switch controller Device Tree Bindings
+-----------------------------------------------------------------------------
+
+Required properties:
+- compatible           : Should be "xlnx,axi-eth-switch-1.00.a"
+- reg                  : Physical base address and size of the TSN registers map.
+
+Example:
+
+       epswitch: tsn_switch@80078000 {
+                        compatible = "xlnx,tsn-eth-switch-1.00.a";
+                        reg = <0x0 0x80078000 0x0 0x4000>;
+       };
