This is a simple utility used to test SPI functionality. It could stand
growing options to support using other test data patterns; this initial
version only issues full duplex transfers, which rules out 3WIRE or

Revert 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26. It broke Sébastien Dugué's
machine and Jeff said (persuasively)
This seems like it will break decades-long-working stuff, in favor of
breaking new ground in our favorite area, "trusting the BIOS."
It's just not worth it for serial ports, IMO. Serial ports are something
that just shouldn't break at this late stage in the game. My new Intel
platform boxes don't even have serial ports, so I question the value of
messing with serial port probing even more... because... just wait a year,
and your box won't have a serial port either! :)
I certainly don't object to the use of platform devices (or isa_driver),
but the probe change seems questionable. That's sorta analagous to
rewriting the floppy driver probe routine. Sure you could do it... but why
risk all that damage and go through debugging all over again?
It seems clear from this report that we cannot, should not, trust BIOS for
something (a) so simple and (b) that has been working for over a decade.
Much discussion ensued and we've decided to have another go at all of this.

While learning about schedstats I found that the documentation in the tree
is old. I updated it and found some interesting stuff like schedstats
version 14 is the same as version and version 13 never saw a kernel
release! Also there are 6 fields in the current schedstats that are not
used anymore. Nick had made them irrelevant in commit
476d139c218e44e045e4bc6d4cc02b010b343939 but never removed them.
Thanks to Rick's perl script who I borrowed some of the updated descriptions
from.

S.Caglar Onur points out that many distributions don't ship a static
zlib. Unfortunately the launcher currently maps virtual device memory
where shared libraries want to go.
The solution is to pre-scan the args to figure out how much memory we
have, then allocate devices above that, rather than down from the top
possible address. This also turns out to be simpler.

Lenovo ThinkPads have a slightly different key map layout from IBM
ThinkPads (fn+f2 and fn+f3 are swapped). Knowing which one we are dealing
with, we can properly set a few more hot keys up by default.
Also, export the correct vendor in the input device, as that information
might be useful to userspace.

It appears that Lenovo decided to break the EC brightness control interface
in a weird way in their latest BIOSes. Fortunately, the old CMOS NVRAM
interface works just fine in such BIOSes.
Add a module parameter that allows the user to select which strategy to use
for brightness control: EC, NVRAM, or both. By default, do both (which is
the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use
NVRAM only on Lenovo ThinkPads.

Make the input layer the default way to deal with thinkpad-acpi hot keys,
but add a kernel config option to retain the old way of doing things.
This means we map a lot more keys to useful stuff by default, and also that
we enable hot key handling by default on driver load (like Windows does).
The documentation for proper use of this resource is also updated.

Add input device support to the hotkey subdriver.
Hot keys that have a valid keycode mapping are reported through the input
layer if the input device is open. Otherwise, they will be reported as
ACPI events, as they were before.
Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY
KEY_UNKNOWN events.
For backwards compatibility purposes, hot keys that used to be reported
through ACPI events are not mapped to anything meaningful by default.
Userspace is supposed to remap them if it wants to use the input device for
hot key reporting.
This patch is based on a patch by Richard Hughes <hughsient@gmail.com>.

Some ThinkPad models, notably the T60 and X60, have a slider switch to
enable and disable the radios. The switch has the capability of
force-disabling the radios in hardware on most models, and it is supposed
to affect all radios (WLAN, WWAN, BlueTooth).
Export the switch state as a sysfs attribute, on ThinkPads where it is
available.
Thanks to Henning Schild for asking for this feature, and for tracking down
the EC register that holds the radio switch state.

The firmware knows how many hot keys it supports, so export this
information in a sysfs attribute.
And the driver knows which keys are always handled by the firmware in all
known ThinkPad models too, so export this information as well in a sysfs
attribute. Unless you know which events need to be handled in a passive
way, do *not* enable hotkeys that are always handled by the firmware.

Revise ACPI HKEY functionality to better interface with the firmware, and
enable up to 32 regular hotkeys, instead of just 16 of them. Ouch.
This takes care of most keys one used to have to do CMOS NVRAM polling on,
and should drop the need for tpb, thinkpad-keys, and other such 5Hz NVRAM
polling power vampires on most modern ThinkPads ;-)
And, just to add insult to injury, this was sort of working since forever
through the procfs interface, but nobody noticed or tried an echo
0xffffffff > /proc/acpi/ibm/hotkey and told me it would generate weird
events. ARGH!
Thanks to Richard Hughes for kicking off the work that ended up with this
discovery, and to Matthew Garret for calling my attention to the fact that
newer ThinkPads were indeed generating ACPI GPEs when such hot keys were
pressed.
