= Spreadtrum SC27XX PMIC eFuse device tree bindings =
Required properties:
- compatible: Should be one of the following.
"sprd,sc2720-efuse"
"sprd,sc2721-efuse"
"sprd,sc2723-efuse"
"sprd,sc2730-efuse"
"sprd,sc2731-efuse"
- reg: Specify the address offset of efuse controller.
- hwlocks: Reference to a phandle of a hwlock provider node.
= Data cells =
Are child nodes of eFuse, bindings of which as described in
bindings/nvmem/nvmem.txt
Example:
sc2731_pmic: pmic@0 {
compatible = "sprd,sc2731";
reg = <0>;
spi-max-frequency = <26000000>;
interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
interrupt-controller;
#interrupt-cells = <2>;
#address-cells = <1>;
#size-cells = <0>;
efuse@380 {
compatible = "sprd,sc2731-efuse";
reg = <0x380>;
#address-cells = <1>;
#size-cells = <1>;
hwlocks = <&hwlock 12>;
/* Data cells */
thermal_calib: calib@10 {
reg = <0x10 0x2>;
};
};
};
= Data consumers =
Are device nodes which consume nvmem data cells.
Example:
thermal {
...
nvmem-cells = <&thermal_calib>;
nvmem-cell-names = "calibration";
};
