You missed an important bit here. Pazquel has a trackpad, doesn't it?
In the "Simplify!" series Stephen made it so that devices that have a
trackpad need to enable it, right?

This is not good and was an important part of "Simplify!" sc7180.dtsi
should only be included by sc7180-trogdor.dtsi.

You seem to be missing the recent downstream changes here.

semtech,input-analog-gain = <0>;
semtech,cs-idle-sleep = "gnd";

You had this right in one of your two v6 series. Not sure why you keep
regressing random things each version...
