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