* Qualcomm Technologies Inc Q6 Integrated connectivity Platform Driver
|
||
|
|
|
||
|
|
This platform driver adds support for the Integrated WLAN that runs
|
||
|
|
on Q6 based platforms. WLAN FW on these architecture runs on Q6. This
|
||
|
|
platform driver communicates with WLAN FW over QMI, WLAN on/off messages
|
||
|
|
to FW are communicated thru this interface. This driver also listens to
|
||
|
|
WLAN PD restart notifications.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "qcom,icnss" for ADRASTEA architecture
|
||
|
|
"qcom,wcn6750" for iWCN architecture
|
||
|
|
"qcom,wcn6450" for evros architecture
|
||
|
|
- reg: Memory regions defined as starting address and size
|
||
|
|
- reg-names: Names of the memory regions defined in reg entry
|
||
|
|
- interrupts: Copy engine interrupt table
|
||
|
|
- qcom,wlan-msa-memory: MSA memory size

|
||
|
|
format to be used for allocations associated between WLAN and SMMU
|
||
|

|
||
|
|
specified in pairs (min, max), units uV. There can
|
||
|
|
be optional load in uA and Regulator settle delay in
|
||
|
|
uS.
|
||
|
|
- qcom,icnss-vadc: VADC handle for vph_pwr read APIs.
|
||
|
|
- qcom,icnss-adc_tm: VADC handle for vph_pwr notification APIs.
|
||
|
|
- io-channels: IIO channel to monitor for vph_pwr power.
|
||
|
|
- io-channel-names: IIO channel name as per the client name.
|
||
|
|
- qcom,smmu-s1-bypass: Boolean context flag to set SMMU to S1 bypass
|
||
|
|
- qcom,wlan-msa-fixed-region: phandle, specifier pairs to children of /reserved-memory
|
||
|
|
- qcom,hyp_disabled: Boolean context flag to disable hyperviser
|
||
|
|
|
||
|
|
