    1 STMicroelectronics STi SATA controller
    2 
    3 This binding describes a SATA device.
    4 
    5 Required properties:
    6  - compatible      : Must be "st,ahci"
    7  - reg             : Physical base addresses and length of register sets
    8  - interrupts      : Interrupt associated with the SATA device
    9  - interrupt-names :   Associated name must be; "hostc"
   10  - clocks          : The phandle for the clock
   11  - clock-names     :   Associated name must be; "ahci_clk"
   12  - phys            : The phandle for the PHY port
   13  - phy-names       :   Associated name must be; "ahci_phy"
   14 
   15 Optional properties:
   16  - resets          : The power-down, soft-reset and power-reset lines of SATA IP
   17  - reset-names     :   Associated names must be; "pwr-dwn", "sw-rst" and "pwr-rst"
   18 
   19 Example:
   20 
   21         /* Example for stih407 family silicon */
   22         sata0: sata@9b20000 {
   23                 compatible      = "st,ahci";
   24                 reg             = <0x9b20000 0x1000>;
   25                 interrupts      = <GIC_SPI 159 IRQ_TYPE_NONE>;
   26                 interrupt-names = "hostc";
   27                 phys            = <&phy_port0 PHY_TYPE_SATA>;
   28                 phy-names       = "ahci_phy";
   29                 resets          = <&powerdown STIH407_SATA0_POWERDOWN>,
   30                                   <&softreset STIH407_SATA0_SOFTRESET>,
   31                                   <&softreset STIH407_SATA0_PWR_SOFTRESET>;
   32                 reset-names     = "pwr-dwn", "sw-rst", "pwr-rst";
   33                 clocks          = <&clk_s_c0_flexgen CLK_ICN_REG>;
   34                 clock-names     = "ahci_clk";
   35         };
