    1 = Mediatek MTK-EFUSE device tree bindings =
    2 
    3 This binding is intended to represent MTK-EFUSE which is found in most Mediatek SOCs.
    4 
    5 Required properties:
    6 - compatible: should be
    7               "mediatek,mt7622-efuse", "mediatek,efuse": for MT7622
    8               "mediatek,mt7623-efuse", "mediatek,efuse": for MT7623
    9               "mediatek,mt8173-efuse" or "mediatek,efuse": for MT8173
   10               "mediatek,mt8192-efuse", "mediatek,efuse": for MT8192
   11               "mediatek,mt8195-efuse", "mediatek,efuse": for MT8195
   12               "mediatek,mt8516-efuse", "mediatek,efuse": for MT8516
   13 - reg: Should contain registers location and length
   14 - bits: contain the bits range by offset and size
   15 
   16 = Data cells =
   17 Are child nodes of MTK-EFUSE, bindings of which as described in
   18 bindings/nvmem/nvmem.txt
   19 
   20 Example:
   21 
   22         efuse: efuse@10206000 {
   23                 compatible = "mediatek,mt8173-efuse";
   24                 reg        = <0 0x10206000 0 0x1000>;
   25                 #address-cells = <1>;
   26                 #size-cells = <1>;
   27 
   28                 /* Data cells */
   29                 thermal_calibration: calib@528 {
   30                         reg = <0x528 0xc>;
   31                 };
   32         };
   33 
   34 = Data consumers =
   35 Are device nodes which consume nvmem data cells.
   36 
   37 For example:
   38 
   39         thermal {
   40                 ...
   41                 nvmem-cells = <&thermal_calibration>;
   42                 nvmem-cell-names = "calibration";
   43         };
