+title: SoC-e SWIP FPGA Ethernet switch function

+
+description:
+  Ethernet switch function of the SoC-e Switch IP (SWIP) FPGA core. The port
+  count and presence of VLAN and STP register blocks depend on the FPGA
+  synthesis configuration.

+  compatible:
+    const: soce,swip-switch-00-04-0c-10
+    description:
+      This compatible identifies the register layout; its suffix gives
+      the offsets of the core version and feature identification
+      registers (0x00, 0x04, 0x0c, and 0x10). Port counts and optional
+      features depend on the FPGA synthesis configuration and are
+      detected at runtime using this register layout.
