+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"
+ - resets : The power-down and soft-reset lines of SATA IP
+ - reset-names : Associated names must be; "pwr-dwn" and "sw-rst"
+ - clocks : The phandle for the clock
+ - clock-names : Associated name must be; "ahci_clk"
+ - phys : The phandle for the PHY device
+ - phy-names : Associated name must be; "ahci_phy"
+
+Example:
+
+ sata0: sata at fe380000 {
+ compatible = "st,ahci";
+ reg = <0xfe380000 0x1000>;
+ interrupts = <GIC_SPI 157 IRQ_TYPE_NONE>;
+ interrupt-names = "hostc";
+ phys = <&miphy365x_phy MIPHY_PORT_0 MIPHY_TYPE_SATA>;
+ phy-names = "ahci_phy";
+ resets = <&powerdown STIH416_SATA0_POWERDOWN>,
+ <&softreset STIH416_SATA0_SOFTRESET>;
+ reset-names = "pwr-dwn", "sw-rst";
+ clocks = <&CLK_S_ICN_REG_0>;
+ clock-names = "ahci_clk";
+ };
