Analog signal amplifier reset
-----------------------------
Required properties:
- compatible: should be one of the following:
"socionext,uniphier-ld11-adamv-reset" - for LD11 SoC
"socionext,uniphier-ld20-adamv-reset" - for LD20 SoC
- #reset-cells: should be 1.
Example:
adamv@57920000 {
compatible = "socionext,uniphier-ld11-adamv",
"simple-mfd", "syscon";
reg = <0x57920000 0x1000>;
adamv_rst: reset {
compatible = "socionext,uniphier-ld11-adamv-reset";
#reset-cells = <1>;
};
other nodes ...
