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";
};
