   13   Bindings for eMMC PHY on Intel's Lightning Mountain SoC, syscon
   14   node is used to reference the base address of eMMC phy registers.
   15 
   16   The eMMC PHY node should be the child of a syscon node with the
   17   required property:
   18 
   19   - compatible:         Should be one of the following:
   20                         "intel,lgm-syscon", "syscon"
   21   - reg:
