* 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"

  - 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

  - clocks: List of clock phandles

  - clock-names: List of clock names corresponding to the "clocks" property

  - iommus: SMMUs and corresponding Stream IDs needed by WLAN

  - qcom,wlan-smmu-iova-address: I/O virtual address range as <start length>

    format to be used for allocations associated between WLAN and SMMU



Optional properties:

  - <supply-name>-supply: phandle to the regulator device tree node

			   optional "supply-name" is "vdd-0.8-cx-mx".

  - qcom,<supply>-config: Specifies voltage levels for supply. Should be

			   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



WLAN SMP2P sub nodes



  - qcom,smp2p_map_wlan_1_in - represents the in smp2p to

				  wlan driver from modem.
