Why is this worrying? AFAIK MSM8939 is pin-compatible with MSM8916, it
uses the same pinctrl driver and compatible = "qcom,msm8916-pinctrl".
You definitely need the same definitions when setting up device trees
for 8939 devices.

In fact most of the MSM8939 device trees that I have seen in the
postmarketOS kernel fork look pretty much like the existing MSM8916
ones, just with the msm8916.dtsi include replaced with msm8939.dtsi.
And I think that's a good thing for consistency and maintenance. :)

I guess if we don't want separate -pins.dtsi anymore this just brings up
the question again if parts of msm8916.dtsi and msm8939.dtsi should be
shared in a .dtsi...
