Luckily, to me it seems that the Phoronix article paints a too dark picture.
As far as I can see, so far the upstream Linux has only removed a few short 
.dtsi files from arch/arm/boot/dts/qcom/ with
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=1701d886a193e2ce856e9c26ffe8db548aaa7694

qcom-ipq8062-smb208.dtsi   (used in OpenWrt by qcom-ipq8062-wg2600hp3.dts )
qcom-ipq8062.dtsi   (used indirectly)
qcom-ipq8064-smb208.dtsi   (used by qcom-ipq8064-fap-421e.dts, 
qcom-ipq8064-onhub.dtsi)
qcom-ipq8064-v2.0-smb208.dtsi  (used by several routers)
qcom-ipq8065-smb208.dtsi   (used by several routers like R7800, XR500, NBG6817)
qcom-ipq8065.dtsi   (used indirectly)

All the main .dts files for those routers are already in the OpenWrt repo. 
And similarly the underlying qcom-ipq8064.dtsi is still in the upstream (as 
it has a few existing devices to prove its usefulness).

E.g. ipq8065.dtsi just refers to "qcom-ipq8064-v2.0.dtsi" that still is 
there, and adds "qcom,ipq8065" into the compatible string. Similarly the 
other .dtsi removed by that commit, look short enough to add into the OpenWrt 
repo when we get to 7.1.

Looking at the kernel.org discussion thread related to that commit, it seems 
that Ansuel tried to propose adding a .dts file using a seemingly not-used 
.dtsi to prove its usefulness, but apparently that did not succeed ?
