| 9 | "sprd,sc2731-efuse" |
| 10 | - reg: Specify the address offset of efuse controller. |
| 11 | - hwlocks: Reference to a phandle of a hwlock provider node. |

| 14 | Are child nodes of eFuse, bindings of which as described in |
| 15 | bindings/nvmem/nvmem.txt |
| 16 | |

| 43 | = Data consumers = |
| 44 | Are device nodes which consume nvmem data cells. |

| 50 | nvmem-cells = <&thermal_calib>; |
