Indeed from a build point of view, there is no dependency so you could take the 2 patches through your respective tree. However, at run-time, the gpio-mlxbf3.c driver fails to load without the pinctrl-mlxbf3.c driver. Should I add a "depends on" in the Kconfig? Then you will have to include both patches in your tree.

Thanks.
