+* Integrated Endpoint Register Block bindings
+
+Optionally, the fsl_enetc driver can probe on the Integrated Endpoint Register
+Block, which preconfigures the FIFO limits for the ENETC ports. This is a node
+with the following properties:
+
+- reg : Specifies the address in the SoC memory space.
+- compatible : Must be "fsl,ls1028a-enetc-ierb".
+
+Example:
+ ierb@1f0800000 {
+ compatible = "fsl,ls1028a-enetc-ierb";
+ reg = <0x01 0xf0800000 0x0 0x10000>;
+ };
