+  Bindings for eMMC PHY on Intel's Lightning Mountain SoC, syscon
+  node is used to reference the base address of eMMC phy registers.
+
+  The eMMC PHY node should be the child of a syscon node with the
+  required property:
+
+  - compatible:         Should be one of the following:
+                        "intel,lgm-syscon", "syscon"
+  - reg:
+      maxItems: 1
+
+properties:
+  compatible:
+      const: intel,lgm-emmc-phy
+
+  "#phy-cells":
+    const: 0
+
+  reg:
+    maxItems: 1
+
+  clocks:
+    maxItems: 1
+
+required:
+  - "#phy-cells"
+  - compatible
+  - reg
+  - clocks
+  - clock-names
+
+examples:
+  - |
+    sysconf: chiptop@e0200000 {
+      compatible = "intel,lgm-syscon", "syscon";
+      reg = <0xe0200000 0x100>;
