-= Mediatek MTK-EFUSE device tree bindings =
-
-This binding is intended to represent MTK-EFUSE which is found in most Mediatek SOCs.
-
-Required properties:
-- compatible: should be
- "mediatek,mt7622-efuse", "mediatek,efuse": for MT7622
- "mediatek,mt7623-efuse", "mediatek,efuse": for MT7623
- "mediatek,mt8173-efuse" or "mediatek,efuse": for MT8173
- "mediatek,mt8192-efuse", "mediatek,efuse": for MT8192
- "mediatek,mt8195-efuse", "mediatek,efuse": for MT8195
- "mediatek,mt8516-efuse", "mediatek,efuse": for MT8516
-- reg: Should contain registers location and length
-- bits: contain the bits range by offset and size
-
-= Data cells =
-Are child nodes of MTK-EFUSE, bindings of which as described in
-bindings/nvmem/nvmem.txt
-
-Example:
-
- efuse: efuse@...06000 {
- compatible = "mediatek,mt8173-efuse";
- reg = <0 0x10206000 0 0x1000>;
- #address-cells = <1>;
- #size-cells = <1>;
-
- /* Data cells */
- thermal_calibration: calib@528 {
- reg = <0x528 0xc>;
- };
- };
-
-= Data consumers =
-Are device nodes which consume nvmem data cells.
-
-For example:
-
- thermal {
- ...
- nvmem-cells = <&thermal_calibration>;
- nvmem-cell-names = "calibration";
- };
