MSM PCI express endpoint
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: should be "qcom,pcie-ep".
|
||||||
|
- reg: should contain PCIe register maps.
|
||||||
|
- reg-names: indicates various resources passed to driver by name.
|
||||||
|
Should be "msi", "dm_core", "elbi", "parf", "phy", "mmio".
|
||||||
|
These correspond to different modules within the PCIe domain.
|
||||||
|
- #address-cells: Should provide a value of 0.
|
||||||
|
- interrupt-parent: Should be the PCIe device node itself here.
|
||||||
|
- interrupts: Should be in the format <0 1 2> and it is an index to the
|
||||||
|
interrupt-map that contains PCIe related interrupts.
|
||||||
|
- #interrupt-cells: Should provide a value of 1.
|
||||||
|
- #interrupt-map-mask: should provide a value of 0xffffffff.
|
||||||
|
- interrupt-map: Must create mapping for the number of interrupts
|
||||||
|
that are defined in above interrupts property.
|
||||||
|
For PCIe device node, it should define 6 mappings for
|
||||||
|
the corresponding PCIe interrupts supporting the
|
||||||
|
specification.
|
||||||
|
- interrupt-names: indicates interrupts passed to driver by name.
|
||||||
|
Should be "int_pm_turnoff", "int_dstate_change",
|
||||||
|
"int_l1sub_timeout", "int_link_up",
|
||||||
|
"int_link_down", "int_bridge_flush_n".
|
||||||
|
- perst-gpio: PERST GPIO specified by PCIe spec.
|
||||||
|
- wake-gpio: WAKE GPIO specified by PCIe spec.
|
||||||
|
- clkreq-gpio: CLKREQ GPIO specified by PCIe spec.
|
||||||
|
- <supply-name>-supply: phandle to the regulator device tree node.
|
||||||
|
Refer to the schematics for the corresponding voltage regulators.
|
||||||
|
vreg-1.8-supply: phandle to the analog supply for the PCIe controller.
|
||||||
|
vreg-0.9-supply: phandle to the analog supply for the PCIe controller.
|
||||||
|
|
||||||
|
Optional Properties:
|
||||||
|
- qcom,<supply-name>-voltage-level: specifies voltage levels for supply.
|
||||||
|
Should be specified in pairs (max, min, optimal), units uV.
|
||||||
|
- clock-names: list of names of clock inputs.
|
||||||
|
Should be "pcie_0_pipe_clk",
|
||||||
|
"pcie_0_aux_clk", "pcie_0_cfg_ahb_clk",
|
||||||
|
"pcie_0_mstr_axi_clk", "pcie_0_slv_axi_clk",
|
||||||
|
"pcie_0_ldo";
|
||||||
|
- max-clock-frequency-hz: list of the maximum operating frequencies stored
|
||||||
|
in the same order of clock names;
|
||||||
|
- qcom,pcie-phy-ver: version of PCIe PHY.
|
||||||
|
- qcom,pcie-link-speed: generation of PCIe link speed. The value could be
|
||||||
|
1, 2 or 3.
|
||||||
|
- Refer to "Documentation/devicetree/bindings/arm/msm/msm_bus.txt" for
|
||||||
|
below optional properties:
|
||||||
|
- qcom,msm-bus,name
|
||||||
|
- qcom,msm-bus,num-cases
|
||||||
|
- qcom,msm-bus,num-paths
