UniPhier reset controller


System reset
------------

Required properties:
- compatible: should be one of the following:
    "socionext,uniphier-sld3-reset" - for sLD3 SoC.
    "socionext,uniphier-ld4-reset"  - for LD4 SoC.
    "socionext,uniphier-pro4-reset" - for Pro4 SoC.
    "socionext,uniphier-sld8-reset" - for sLD8 SoC.
    "socionext,uniphier-pro5-reset" - for Pro5 SoC.
    "socionext,uniphier-pxs2-reset" - for PXs2/LD6b SoC.
    "socionext,uniphier-ld11-reset" - for LD11 SoC.
    "socionext,uniphier-ld20-reset" - for LD20 SoC.
- #reset-cells: should be 1.

Example:

	sysctrl@61840000 {
		compatible = "socionext,uniphier-ld11-sysctrl",
			     "simple-mfd", "syscon";
		reg = <0x61840000 0x4000>;

		reset {
			compatible = "socionext,uniphier-ld11-reset";
			#reset-cells = <1>;
		};

		other nodes ...
	};


Media I/O (MIO) reset, SD reset
-------------------------------

Required properties:
- compatible: should be one of the following:
    "socionext,uniphier-sld3-mio-reset" - for sLD3 SoC.
    "socionext,uniphier-ld4-mio-reset"  - for LD4 SoC.
    "socionext,uniphier-pro4-mio-reset" - for Pro4 SoC.
    "socionext,uniphier-sld8-mio-reset" - for sLD8 SoC.
    "socionext,uniphier-pro5-sd-reset"  - for Pro5 SoC.
    "socionext,uniphier-pxs2-sd-reset"  - for PXs2/LD6b SoC.
    "socionext,uniphier-ld11-mio-reset" - for LD11 SoC.
    "socionext,uniphier-ld20-sd-reset"  - for LD20 SoC.
- #reset-cells: should be 1.

Example:

	mioctrl@59810000 {
		compatible = "socionext,uniphier-ld11-mioctrl",
			     "simple-mfd", "syscon";
		reg = <0x59810000 0x800>;

		reset {
			compatible = "socionext,uniphier-ld11-mio-reset";
			#reset-cells = <1>;
		};

		other nodes ...
	};


Peripheral reset
----------------

Required properties:
- compatible: should be one of the following:
    "socionext,uniphier-ld4-peri-reset"  - for LD4 SoC.
    "socionext,uniphier-pro4-peri-reset" - for Pro4 SoC.
    "socionext,uniphier-sld8-peri-reset" - for sLD8 SoC.
    "socionext,uniphier-pro5-peri-reset" - for Pro5 SoC.
    "socionext,uniphier-pxs2-peri-reset" - for PXs2/LD6b SoC.
    "socionext,uniphier-ld11-peri-reset" - for LD11 SoC.
    "socionext,uniphier-ld20-peri-reset" - for LD20 SoC.
- #reset-cells: should be 1.

Example:

	perictrl@59820000 {
		compatible = "socionext,uniphier-ld11-perictrl",
			     "simple-mfd", "syscon";
		reg = <0x59820000 0x200>;

		reset {
			compatible = "socionext,uniphier-ld11-peri-reset";
			#reset-cells = <1>;
		};

		other nodes ...
	};
