Seconded. This actually happens a lot; I don't mean to pick on the MFD drivers especially. Sometimes the best way to answer a new config question is to RTFS, which is a bit tedious.
For example, the "ACPI 4.0 Power Meter" (CONFIG_ACPI_POWER_METER). To me, a power meter is a large glass-encased object containing a spinning aluminum disc and mounted on the wall of my house which determines my monthly power bill.
How this relates to ACPI 4.0 firmware is unclear. Indeed, how do I figure out of I have ACPI 4.0 firmware?
Then there's CONFIG_SFI. Nowhere in the Kconfig text does it explain that it's intended as a lightweight alternative to ACPI for hand-held devices and not for desktop machines.
Then there are the PCI_GO* options... I still have no idea. (I just pick "any", figuring it's the most likely to work.)
I think the CONFIG_PCI help text could use some updating.
The CONFIG_PCIEPORTBUS is unnecessarily confusing. It doesn't clearly explain, if I have PCI express slots on my computer: - Do I actually need this to boot? - Does it do anything besides enable a config submenu?
CONFIG_MCA (admittedly a critically endangered interest group, but still listed as "Maintained" in MAINTAINERS) stresses the importance of the web site address given in in Documentation/mca.txt, which is http://www.dgmicro.com/mca/. That domain no longer exists (expired March '07) and has been grabbed by a squatter. It can be found on the wayback machine at http://web.archive.org/web/20070225223240/http://www.dgmicro.com/mca/ and gives a last update date of 1999.
It would be easy to go on...
