Hello, The Maxim77802 PMIC driver uses a boolean Kconfig symbol but there isn't really a reason to require the driver to be built-in.
It is true that since the PMIC provides clocks and regulators that could be critical on a system, most integrators are not going to build it as a module but it could be useful for multi-platform or distribution kernels that support different systems by building as much as possible as module. Besides this series, a patch for the max77686 regulator driver is needed or the MFD max77686 driver module won't be installed by kbuild. I didn't include the patch in this series to avoid cross-subsystems churn for the maintainers and also because I don't consider that a regression since it was not possible to build the driver as a module before anyways. Also, all the defconfigs in mainline that enable the MFD max77686 driver Kconfig symbol are using =y of course so it shouldn't be an issue to get this set merged, before the max77686 regulator patch already posted [0].
