+Qualcomm IPQ806x SATA PHY Controller
|
||
|
|
+------------------------------------
|
||
|
|
+
|
||
|
|
+SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
|
||
|
|
+Each SATA PHY controller should have its own node.
|
||
|
|
+
|
||
|
|
+Required properties:
|
||
|
|
+- compatible: compatible list, contains "qcom,ipq806x-sata-phy"
|
||
|
|
+- reg: offset and length of the SATA PHY register set;
|
||
|
|
+- #phy-cells: must be zero
|
||
|
|
+- clocks: must be exactly one entry
|
||
|
|
+- clock-names: must be "cfg"
|
||
|
|
+
|
||
|
|
+Example:
|
||
|
|
+ sata_phy: sata-phy@1b400000 {
|
||
|
|
+ compatible = "qcom,ipq806x-sata-phy";
|
||
|
|
+ reg = <0x1b400000 0x200>;
|
||
|
|
+
|
||
|
|
+ clocks = <&gcc SATA_PHY_CFG_CLK>;
|
||
|
|
+ clock-names = "cfg";
|
||
|
|
+
|
||
|
|
+ #phy-cells = <0>;
|
||
|
|
+ };
