dt-bindings: nvmem: Convert rockchip-efuse bindings to yaml

= Rockchip eFuse device tree bindings =

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,rk3328-efuse" - for RK3328 SoCs.

  - "rockchip,rk3368-efuse" - for RK3368 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"

Optional properties:

- rockchip,efuse-size: Should be exact eFuse size in byte, the eFuse

  size in property <reg> will be invalid if define this property.

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";

	};
