Required properties:
- compatible: Should be one of the following.
- "rockchip,rk3066a-efuse" - for RK3066a SoCs.
- "rockchip,rk3188-efuse" - for RK3188 SoCs.
- "rockchip,rk3228-efuse" - for RK3228 SoCs.
- "rockchip,rk3288-efuse" - for RK3288 SoCs.
- "rockchip,rk3399-efuse" - for RK3399 SoCs.
- reg: Should contain the registers location and exact eFuse size
- clocks: Should be the clock id of eFuse
- clock-names: Should be "pclk_efuse"
Deprecated properties:
- compatible: "rockchip,rockchip-efuse"
Old efuse compatible value compatible to rk3066a, rk3188 and rk3288
efuses
= Data cells =
Are child nodes of eFuse, bindings of which as described in
bindings/nvmem/nvmem.txt
Example:
efuse: efuse@ffb40000 {
compatible = "rockchip,rk3288-efuse";
reg = <0xffb40000 0x20>;
#address-cells = <1>;
#size-cells = <1>;
clocks = <&cru PCLK_EFUSE256>;
clock-names = "pclk_efuse";
/* Data cells */
cpu_leakage: cpu_leakage {
reg = <0x17 0x1>;
};
};
= Data consumers =
Are device nodes which consume nvmem data cells.
Example:
cpu_leakage {
...
nvmem-cells = <&cpu_leakage>;
nvmem-cell-names = "cpu_leakage";
};
