Subject: [PATCH 0/4] mfd: max77686: Allow the driver to be built as a module

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].

Best regards,
Javier
