I saw this warning as well when I ran the DT schema check.

However I think this is a false warning as the gpio-hog schema
requires "*-hog" in the name, but the MT7986 pinctrl schema doesn't
allow for this.

Looking at other examples of gpio-hog I can see in
arch/arm64/boot/dts/mediatek/pumpkin-common.dtsi some hogs that are
very similar to my new one with "*-hog" in the name under a node with
"gpio-controller". Another example is
arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts which has a
hog ("asm_sel") under "pio" which is the same location as my new hog,
but this one seems to violate the requirement for "hog" to be in the
name.
