* MSM Universal Flash Storage (UFS) PHY
|
|
|
|
UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
|
|
Each UFS PHY node should have its own node.
|
|
|
|
To bind UFS PHY with UFS host controller, the controller node should
|
|
contain a phandle reference to UFS PHY node.
|
|
|
|
Required properties:
|
|
- compatible : compatible list, contains "qcom,ufsphy"
|
|
- reg : <registers mapping>
|
|
- vdda-phy-supply : phandle to main PHY supply for analog domain
|
|
- vdda-pll-supply : phandle to PHY PLL and Power-Gen block power supply
|
|
|
|
Optional properties:
|
|
- vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
|
|
- vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply
|
|
|
|
Example:
|
|
|
|
ufsphy1: ufsphy@0xfc597000 {
|
|
compatible = "qcom,ufsphy";
|
|
reg = <0xfc597000 0x800>;
|
|
vdda-phy-supply = <&pma8084_l4>;
|
|
vdda-pll-supply = <&pma8084_l12>;
|
|
vdda-phy-max-microamp = <50000>;
|
|
vdda-pll-max-microamp = <1000>;
|
|
};
|
|
|
|
ufshc@0xfc598000 {
|
|
...
|
|
ufs-phy = <&ufsphy1>;
|
|
};
