TI PCI Controllers
PCIe Designware Controller
- compatible: Should be "ti,dra7-pcie""
- reg : Two register ranges as listed in the reg-names property
- reg-names : The first entry must be "ti-conf" for the TI specific registers
The second entry must be "rc-dbics" for the designware pcie
registers
The third entry must be "config" for the PCIe configuration space
- phys : list of PHY specifiers (used by generic PHY framework)
- phy-names : must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
number of PHYs as specified in *phys* property.
- ti,hwmods : Name of the hwmod associated to the pcie, "pcie<X>",
where <X> is the instance number of the pcie from the HW spec.
- interrupts : Two interrupt entries must be specified. The first one is for
main interrupt line and the second for MSI interrupt line.
- #address-cells,
#size-cells,
#interrupt-cells,
device_type,
ranges,
num-lanes,
interrupt-map-mask,
interrupt-map : as specified in ../designware-pcie.txt
Example:
axi {
compatible = "simple-bus";
#size-cells = <1>;
#address-cells = <1>;
ranges = <0x51000000 0x51000000 0x3000

reg-names = "rc_dbics", "ti_conf", "config";
interrupts = <0 232 0x4>, <0 233 0x4>;
