Kernel-4.18.0-80.el8_ahci-st

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";
};
