| 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: |
