| 2 | ====================================== |
| 3 | |
| 4 | The device tree node which describes the operation of the Intel Pantherpoint |
| 5 | SATA device is as follows: |
| 6 | |
| 7 | Required properties : |
| 8 | - compatible = "intel,pantherpoint-ahci" |
| 9 | - intel,sata-mode : string, one of: |
| 10 | "ahci" : Use AHCI mode (default) |
| 11 | "combined" : Use combined IDE + legacy mode |
| 12 | "plain-ide" : Use plain IDE mode |
| 13 | - intel,sata-port-map : Which SATA ports are enabled, bit 0=enable first port, |
| 14 | bit 1=enable second port, etc. |
| 15 | - intel,sata-port0-gen3-tx : Value for the IOBP_SP0G3IR register |
| 16 | - intel,sata-port1-gen3-tx : Value for the IOBP_SP1G3IR register |
| 17 | |
| 18 | Example |
| 19 | ------- |
| 20 | |
| 21 | sata { |
| 22 | compatible = "intel,pantherpoint-ahci"; |
| 23 | intel,sata-mode = "ahci"; |
| 24 | intel,sata-port-map = <1>; |
| 25 | intel,sata-port0-gen3-tx = <0x00880a7f>; |
| 26 | }; |
