The includes are still not correct as far as I can tell. If you look
at Stephen's solution in "Simplify!" plus his fixup that your series
is based on, AKA ("arm64: dts: qcom: Remove duplicate sc7180-trogdor
include on lazor/homestar") then I believe the correct thing to do
here is:

1. Go back to v9

2. Remove the include of "sc7180-trogdor.dtsi" from the pazquel and
kingoftown .dtsi files.

3. Every place in pazquel and kingoftown that has an include of
"sc7180.dtsi" replace that with "sc7180-trogdor.dtsi"


I'm curious: did you try compiling your patches? Do they work? They
don't seem to for me. It's expected that when you post patches that
you have, at the very least, compile tested them. Given how much of
trogdor works upstream I'd also expect you to have actually boot
tested as many of the boards that you have hardware for.
