@ -96,6 +96,17 @@ Optional properties:
- qcom,coexist-gpio-pin : gpio pin number information to support coex
which will be used by wifi firmware.
* Subnodes
The ath10k wifi node can contain one optional firmware subnode.
Firmware subnode is needed when the platform does not have TustZone.
The firmware subnode must have:
- iommus:
Usage: required
Value type: <prop-encoded-array>
Definition: A list of phandle and IOMMU specifier pairs.
Example (to supply PCI based wifi block details):
In this example, the node is defined as child node of the PCI controller.
