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"
