+STMicroelectronics STi SATA controller
+
+This binding describes a SATA device.
+
+Required properties:
+ - compatible	   : Must be "st,ahci"
+ - reg		   : Physical base addresses and length of register sets
+ - interrupts	   : Interrupt associated with the SATA device
+ - interrupt-names :   Associated name must be; "hostc"
+ - clocks	   : The phandle for the clock
+ - clock-names	   :   Associated name must be; "ahci_clk"
+ - phys		   : The phandle for the PHY port
+ - phy-names	   :   Associated name must be; "ahci_phy"
+
+Optional properties:
+ - resets	   : The power-down, soft-reset and power-reset lines of SATA IP
+ - reset-names	   :   Associated names must be; "pwr-dwn", "sw-rst" and "pwr-rst"
+
+Example:
+
+	/* Example for stih407 family silicon */
+	sata0: sata@9b20000 {
+		compatible	= "st,ahci";
+		reg		= <0x9b20000 0x1000>;
+		interrupts	= <GIC_SPI 159 IRQ_TYPE_NONE>;
+		interrupt-names	= "hostc";
+		phys		= <&phy_port0 PHY_TYPE_SATA>;
+		phy-names	= "ahci_phy";
+		resets		= <&powerdown STIH407_SATA0_POWERDOWN>,
+				  <&softreset STIH407_SATA0_SOFTRESET>,
+				  <&softreset STIH407_SATA0_PWR_SOFTRESET>;
+		reset-names	= "pwr-dwn", "sw-rst", "pwr-rst";
+		clocks		= <&clk_s_c0_flexgen CLK_ICN_REG>;
+		clock-names	= "ahci_clk";
+	};
