   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         };
