+ 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:
+ contains:
+ const: intel,lgm-emmc-phy
+
+ "#phy-cells":
+ const: 0
+
+ reg:
+ maxItems: 1
+
+ clocks:
+ maxItems: 1
+
+ clock-names:
+ maxItems: 1
+
+required:
+ - "#phy-cells"
+ - compatible
+ - reg
+ - clocks
+ - clock-names
+
+examples:
+ - |
+ sysconf: chiptop@e0200000 {
+ compatible = "intel,lgm-syscon", "syscon";
+ reg = <0xe0200000 0x100>;
+
+ emmc-phy: emmc-phy@a8 {
+ compatible = "intel,lgm-emmc-phy";
+ reg = <0x00a8 0x10>;
+ clocks = <&emmc>;
