description: |+
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:
maxItems: 1
clocks:
maxItems: 1
required:
- "#phy-cells"
- compatible
- reg
- clocks
additionalProperties: false
examples:
- |
sysconf: chiptop@e0200000 {
compatible = "intel,lgm-syscon", "syscon";
reg = <0xe0200000 0x100>;
#address-cells = <1>;
#size-cells = <1>;
emmc_phy: emmc-phy@a8 {
compatible = "intel,lgm-emmc-phy";
reg = <0x00a8 0x10>;
clocks = <&emmc>;
#phy-cells = <0>;
