Sure Bjorn.
I have sent v2 for the patch "arm64: dts: qcom: sc7180: Add WCN3990 WLAN
module device node", where I have squashed this change as well.
Thanks,
Rakesh.

The MSA memory is at a fixed offset, which will be
a part of reserved memory. Add this flag to indicate
that wifi in sc7180 will use a fixed memory for MSA.
