Subject[PATCH v3 04/19] dt-bindings: Add Qualcomm USB SuperSpeed PHY bindings
Date
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:

- "intel,lgm-syscon", "syscon"
- - reg:
- maxItems: 1
