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>;
};
