[Bryan O'Donoghue <bryan.odonoghue@linaro.org>]

From: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@linaro.org>

Binding description for Qualcomm's Synopsys 1.0.0 SuperSpeed phy
controller embedded in QCS404.

Based on Sriharsha Allenki's <sallenki@codeaurora.org> original
definitions.

[bod: converted to yaml format]

-  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:

-
-  clocks:
-    maxItems: 1
-
-required:
-  - "#phy-cells"
-  - compatible
-  - reg
