1 | * Qualcomm AHCI SATA Controller |
| 2 | ||
| 3 | SATA nodes are defined to describe on-chip Serial ATA controllers. | |
| 4 | Each SATA controller should have its own node. | |
| 5 | ||
| 6 | Required properties: | |
| 7 | - compatible : compatible list, must contain "generic-ahci" | |
| 8 | - interrupts : <interrupt mapping for SATA IRQ> | |
| 9 | - reg : <registers mapping> | |
| 10 | - phys : Must contain exactly one entry as specified | |
| 11 | in phy-bindings.txt | |
| 12 | - phy-names : Must be "sata-phy" | |
| 13 | ||
| 14 | Required properties for "qcom,ipq806x-ahci" compatible: | |
| 15 | - clocks : Must contain an entry for each entry in clock-names. | |
| 16 | - clock-names : Shall be: | |
| 17 | "slave_iface" - Fabric port AHB clock for SATA | |
| 18 | "iface" - AHB clock | |
| 19 | "core" - core clock | |
| 20 | "rxoob" - RX out-of-band clock | |
| 21 | "pmalive" - Power Module Alive clock | |
| 22 | - assigned-clocks : Shall be: | |
| 23 | SATA_RXOOB_CLK | |
| 24 | SATA_PMALIVE_CLK | |
| 25 | - assigned-clock-rates : Shall be: | |
| 26 | 100Mhz (100000000) for SATA_RXOOB_CLK | |
| 27 | 100Mhz (100000000) for SATA_PMALIVE_CLK | |
| 28 | ||
| 29 | Example: | |
| 30 | sata@29000000 { | |
| 31 | compatible = "qcom,ipq806x-ahci", "generic-ahci"; | |
| 32 | reg = <0x29000000 0x180>; | |
