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: |
