Subject[PATCH] arm64: dts: qcom: sc7180: Add missing properties for Wifi node
The wlan firmware memory is statically mapped in
the Trusted Firmware, hence the wlan driver does
not need to map/unmap this region dynamically.

Hence add the property to indicate the wlan driver
to not map/unamp the firmware memory region

Also add the chain1 voltage supply for wlan.

Signed-off-by: Rakesh Pillai <>
This patch is created on top of the change by
Douglas Anderson.

Also the dt-bindings for the chain1 voltage supply
is added by the below patch series:
