* 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>;
};
