* Samsung 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 "samsung,exynos5-sata-phy"
- reg : <registers mapping>
Example:
sata@ffe07000 {
compatible = "samsung,exynos5-sata-phy";
reg = <0xffe07000 0x1000>;
};

Samsung 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 "samsung,exynos5250-sata-phy"
- reg : offset and length of the SATA PHY register set;
- #phy-cells : from the generic phy bindings;
Example:
sata_phy: sata-phy@12170000 {
compatible = "samsung,exynos5250-sata-phy";
reg = <0x12170000 0x1ff>;
clocks = <&clock 287>;

};
Device-Tree bindings for sataphy i2c client driver
--------------------------------------------------
Required properties:
compatible: Should be "samsung,exynos-sataphy-i2c"
- reg: I2C address of the sataphy i2c device.
Example:
sata_phy_i2c:sata-phy@38 {
compatible = "samsung,exynos-sataphy-i2c";
reg = <0x38>;
