STMicroelectronics STi SATA controller
This binding describes a SATA device.
Required properties:
- compatible : Must be "st,sti-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@fe380000 {
compatible = "st,sti-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_a0_ls CLK_ICN_REG>;
clock-names = "ahci_clk";
};
