1 | TI PCI Controllers |
| 2 | ||
| 3 | PCIe Designware Controller | |
| 4 | - compatible: Should be "ti,dra7-pcie"" | |
| 5 | - reg : Two register ranges as listed in the reg-names property | |
| 6 | - reg-names : The first entry must be "ti-conf" for the TI specific registers | |
| 7 | The second entry must be "rc-dbics" for the designware pcie | |
| 8 | registers | |
| 9 | The third entry must be "config" for the PCIe configuration space | |
| 10 | - phys : list of PHY specifiers (used by generic PHY framework) | |
| 11 | - phy-names : must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the | |
| 12 | number of PHYs as specified in *phys* property. | |
| 13 | - ti,hwmods : Name of the hwmod associated to the pcie, "pcie<X>", | |
| 14 | where <X> is the instance number of the pcie from the HW spec. | |
| 15 | - interrupts : Two interrupt entries must be specified. The first one is for | |
| 16 | main interrupt line and the second for MSI interrupt line. | |
| 17 | - #address-cells, | |
| 18 | #size-cells, | |
| 19 | #interrupt-cells, | |
| 20 | device_type, | |
| 21 | ranges, | |
| 22 | num-lanes, | |
| 23 | interrupt-map-mask, | |
| 24 | interrupt-map : as specified in ../designware-pcie.txt | |

26 | Optional Property: |
| 27 | - gpios : Should be added if a gpio line is required to drive PERST# line | |
