I see the sequence as:

1. You merge mediatek,mt6797-pinctrl.yaml into mediatek,mt6779-pinctrl.yaml; then
2. Adding MT6765 documentation to mediatek,mt6779-pinctrl.yaml; then
3. Adding support for MT6735, documentation goes again to 6779-pinctrl.

This means that you're working with mediatek,mt6779-pinctrl.yaml :-)

P.S.: That was also a suggestion about how to split things per-commit!

Cheers,
Angelo
