Hi all,
I was looking at the openSUSE 13.1 kernel config and noticed the
following settings which I'd like to discuss.
# CONFIG_BATMAN_ADV_NC is not set
Given that all other CONFIG_BATMAN_ADV_* options are enabled, what is
the rationale for not enabling CONFIG_BATMAN_ADV_NC too? I'm not using
Batman so I don't care personally, but for consistency it seems this
option should be enabled.
# CONFIG_GPIO_SCH is not set
# CONFIG_GPIO_PCH is not set
These were disabled on purpose by commit f554d8b2:

Date: Sun May 13 22:31:50 2012 -0400
Disabled more Intel embedded drivers.
Disabled:
- CONFIG_GPIO_LANGWELL
- CONFIG_GPIO_PCH
- CONFIG_GPIO_SCH
But meanwhile (kernel v3.5) the gpio-sch driver was added support for
the Intel Centerton microprocessor family, which I'm fairly sure we want
to fully support.
I am also wondering about gpio-pch because it supports a chipset for
Tunnel Creek (Intel Atom E6xx) processors since kernel v3.3, and I don't
quite understand why we wouldn't want to support these. I seem to recall
it was already discussed but I can no longer find the discussion so I
can't verify. But I see we have CONFIG_PCH_PHUB=m, CONFIG_PCH_GBE=m and
CONFIG_PCH_DMA=m, so CONFIG_GPIO_PCH=m would seem consistent.
# CONFIG_INTEL_POWERCLAMP
While I don't expect this driver to get widely used, it could be useful
in specific cases, like machines working in extreme conditions,
temporary workaround to fan or air conditioning system failure, or
debugging. The driver is small and unintrusive, so I see no downside to
including it.
