wil6210 - Qualcomm Technologies Inc. 802.11ad Wireless Driver
|
||
|
|
|
||
|
|
wil6210 driver is responsible for managing 802.11ad chipset
|
||
|
|
connected to MSM over PCIe interface.
|
||
|
|
|
||
|
|
The platform data is needed in order to perform proper
|
||
|
|
bus-scaling and SMMU initialization by the driver.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible: "qcom,wil6210"
|
||
|
|
- qcom,smmu-support: Boolean flag indicating whether PCIe has SMMU support
|
||
|
|
- qcom,smmu-s1-en: Boolean flag indicating whether SMMU stage1 should be enabled
|
||
|
|
- qcom,smmu-fast-map: Boolean flag indicating whether SMMU fast mapping should be enabled
|
||
|
|
- qcom,smmu-coherent: Boolean flag indicating SMMU dma and page table coherency
|
||
|
|
- qcom,smmu-mapping: specifies the base address and size of SMMU space
|
||
|
|
- qcom,pcie-parent: phandle for the PCIe root complex to which 11ad card is connected
|
||
|
|
- Refer to "Documentation/devicetree/bindings/arm/msm/msm_bus.txt" for
|
||
|
|
the below optional properties:
|
||
|
|
- qcom,msm-bus,name
|
||
|
|
- qcom,msm-bus,num-cases
|
||
|
|
- qcom,msm-bus,num-paths
|
||
|
|
- qcom,msm-bus,vectors-KBps
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- qcom,sleep-clk-en: GPIO for sleep clock used for low power modes by 11ad card
|
||
|
|
- qcom,wigig-en: Enable GPIO connected to 11ad card
|
||
|
|
- qcom,wigig-dc: Enable DC to DC GPIO connected to 11ad card
|
||
|
|
- qcom,use-ext-supply: Boolean flag to indicate if 11ad SIP uses external power supply
|
||
|
|
- vdd-supply: phandle to 11ad VDD regulator node
|
||
|
|
- vddio-supply: phandle to 11ad VDDIO regulator node
|
||
|
|
- qcom,use-ext-clocks: Boolean flag to indicate if 11ad SIP uses external clocks
|
||
|
|
- clocks : List of phandle and clock specifier pairs
|
||
|
|
- clock-names : List of clock input name strings sorted in the same
|
||
|
|
order as the clocks property.
|
||
|
|
- qcom,keep-radio-on-during-sleep: Boolean flag to indicate if to suspend to d3hot
|
||
|
|
instead of turning off the device
|
||
|
|
|
||
|
|
