= 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>;
|
|
|
|

|
|
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";
|

};
