| 2 | ----------------------------------------------------------- |
| 3 | |
| 4 | Required properties: |
| 5 | - compatible = "ibm,i2c-fsi"; |
| 6 | - reg = < address size >; : The FSI CFAM address and address |
| 7 | space size. |
| 8 | - #address-cells = <1>; : Number of address cells in child |
| 9 | nodes. |
| 10 | - #size-cells = <0>; : Number of size cells in child nodes. |
| 11 | - child nodes : Nodes to describe busses off the I2C |
| 12 | master. |
| 13 | |
| 14 | Child node required properties: |
| 15 | - reg = < port number > : The port number on the I2C master. |
| 16 | |
| 17 | Child node optional properties: |
| 18 | - child nodes : Nodes to describe devices on the I2C |
| 19 | bus. |

| 26 | #address-cells = <1>; |
