Add a YAML schema to use the host controller driver with the
eMMC PHY on Intel's Lightning Mountain SoC.

+ 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:
You need to drop 'contains'. That implies other strings can also be
present.
Sure, I will drop contains..
+ const: intel,lgm-emmc-phy
+
+ "#phy-cells":
+ const: 0
+
+ reg:
+ maxItems: 1
+
+ clocks:
+ maxItems: 1
+
+ clock-names:
+ maxItems: 1
Drop maxItems. It should be:

const: emmcclk

Or just drop clock-names because you don't really need *-names when
there is only 1.

Noted, fix it.

With Best Regards
Vadivel
