| 2 | |
| 3 | SATA host controller nodes are defined to describe on-chip Serial ATA |
| 4 | controllers. Each SATA controller (pair of ports) have its own node. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible : Shall contain: |
| 8 | * "apm,xgene-ahci" |
| 9 | - reg : First memory resource shall be the AHCI memory |
| 10 | resource. |
| 11 | Second memory resource shall be the host controller |
| 12 | core memory resource. |
| 13 | Third memory resource shall be the host controller |
| 14 | diagnostic memory resource. |
| 15 | 4th memory resource shall be the host controller |
| 16 | AXI memory resource. |
| 17 | 5th optional memory resource shall be the host |
| 18 | controller MUX memory resource if required. |
| 19 | - interrupts : Interrupt-specifier for SATA host controller IRQ. |
| 20 | - clocks : Reference to the clock entry. |
| 21 | - phys : A list of phandles + phy-specifiers, one for each |
| 22 | entry in phy-names. |
| 23 | - phy-names : Should contain: |
| 24 | * "sata-phy" for the SATA 6.0Gbps PHY |
| 25 | |
| 26 | Optional properties: |
| 27 | - dma-coherent : Present if dma operations are coherent |
| 28 | - status : Shall be "ok" if enabled or "disabled" if disabled. |
| 29 | Default is "ok". |
