Subject[PATCH 0/3] pc104: Mask PC/104 Kconfig options
Message-ID<sY9Oh-4Tu-3@gated-at.bofh.it>
PC/104 form factor devices serve a specific niche of embedded system
users. Since PC/104 devices and hardware are typically used by just a
subset of Linux users, it would be appropriate to filter PC/104 related
Kconfig options for those uninterested.

This patchset introduces the PC104 Kconfig option, and uses it to mask
PC/104 specific device drivers and options, so that only those users
interested in PC/104 related Kconfig options are exposed to them.

PC/104 drivers should be hidden on machines which do not support PC/104
devices. This patch adds the PC104 Kconfig option as a dependency for
the relevant PC/104 device driver Kconfig options.

Now the question is how to merge this one.  Let me know if you
want me to take this one via IIO after the first patch is in.
If you want to take it another route I'm fine with that.

This is such a simple patchset that I envision Greg K-H picking up all
three patches via driver-core; however, I'm pretty indifferent about the
ultimate path in the end. I'll leave it up to Greg K-H to decide.

As long as Greg merges the first patch we can merge the two
others orthogonally I think.

It's just Kconfig symbols, not things that break compile.

(But I bet someone will come with automated warnings about
unused symbols in the kernel...)

Tell me when/if the PC104 option is merged and I can merge the GPIO
patch.
