Hi Kevin,

1. Since the first beginning version of MT8186 dts is under review [1],
so I can NOT update svs content in dts unless the first beginning
version is accepted.  And I will update it once the first beginning dts
is accpeted.

2. MT8186 svs was tested on MT8186 chromebook prototype and comparing
the register results between chromebook prototype's and MediaTek
internal evaluation by feeding the same input e-fuse data.

Here's the svs content in mt8186.dtsi on chromebook prototype.
/ {
	soc {
		/* ... */
+		svs: svs@...0b000 {
+			compatible = "mediatek,mt8186-svs";
+			reg = <0 0x1100b000 0 0x1000>;
+			interrupts = <GIC_SPI 142 IRQ_TYPE_LEVEL_HIGH>;
+			clocks = <&infracfg_ao CLK_INFRA_AO_THERM>;
+			clock-names = "main";
+			nvmem-cells = <&svs_calibration>, <&lvts_e_data1>;
+			nvmem-cell-names = "svs-calibration-data", "t-
calibration-data";
+			resets = <&infracfg_rst 1>;
+			reset-names = "svs_rst";
+		};
		/* ... */
		efuse: efuse@...b0000 {
			/* ... */
+			svs_calibration: calib {
+				reg = <0x550 0x50>;
+			};
			/* ... */
		};
		/* ... */
	};
};

Yes, I use Roger Lu's svs v22 [2] as the codebase and compare the
results between with MT8186 svs series or without it on the MT8183
chromebook as well.  The comparison result is approved by Roger.

The svs content of MT8186 is given above.
I will update it once the first beginning dts is accpeted.
