Report output values as 1/1000 of earth gravity.
Output values from lis3 can be read from sysfs position entry and from
input device. Input device can be accessed as event device and as
joystick device. Joystick device can be in two modes. Meaning of the
output values varies from case to case depending on the chip type and
configuration (scale). Only joystick interface in JS_CORR_BROKEN mode
returned somehow similar output values in different configurations.
Joystick device is in that state by default in case of lis3.
Position sysfs entry, input event device and raw joystick device have been
little bit broken since meaning of the output values has been varied
between 12 and 8 bit devices. Applications which relayed on those methods
failed if the chip is different than the expected one.
This patch converts output values to mean similar thing in different
configurations. Both 8 and 12 bit devices reports now same acceleration
values. If somebody implements full scale support to the driver, output
values will still mean the same. Scaling factor and input device range
must be updated in that case.
Joystick interface in JS_CORR_BROKEN mode is not touched by this patch.
All other interfaces have different scale after this change. For 12 bit
device scaling factor is 0.977 which keeps scaled and unscaled values are
quite close to each others. For 8 bit device, scaled values are 18 times
bigger than unscaled values.

Implement selftest feature as specified by chip manufacturer. Control:
read selftest sysfs entry
Response: "OK x y z" or "FAIL x y z"
where x, y, and z are difference between selftest mode and normal mode.
Test is passed when values are within acceptance limit values.
Acceptance limits are provided via platform data. See chip spesifications
for acceptance limits. If limits are not properly set, OK / FAIL decision
is meaningless. However, userspace application can still make decision
based on the numeric x, y, z values.
Selftest is meant for HW diagnostic purposes. It is not meant to be
called during normal use of the chip. It may cause false interrupt
events. Selftest mode delays polling of the normal results but it doesn't
cause wrong values. Chip must be in static state during selftest. Any
acceration during the test causes most probably failure.

This new revision of the IP adds some improvements to the MCI already
present in several Atmel SOC.
Some new registers are added and a particular way of handling DMA
interaction lead to a new sequence in function call which is backward
compatible: On MCI2, we must set the DMAEN bit to enable the DMA
handshaking interface. This must happen before the data transfer command
is sent.
A new function is able to differentiate MCI2 code and is based on
knowledge of processor id (cpu_is_xxx()).

Some people run general-purpose distribution kernels on netbooks with
a card that is physically non-removable or logically non-removable
(e.g. used for /home) and cannot be cleanly unmounted during suspend.
Add a module parameter to set whether cards are assumed removable or
non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME.
In general, it is not possible to tell whether a card present in an MMC
slot after resume is the same that was there before suspend. So there are
two possible behaviours, each of which will cause data loss in some cases:
CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed
during suspend. Any filesystem on them must be unmounted before suspend;
otherwise, buffered writes will be lost.
CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during
suspend. They must not be swapped during suspend; otherwise, buffered
writes will be flushed to the wrong card.
Currently the choice is made at compile time and this allows that to be
overridden at module load time.

The difference between simple_strtoul() and simple_strtoull() is just
the size of the variable used to keep track of the sum of characters
converted to numbers:
unsigned long simple_strtoul() {...}
unsigned long long simple_strtoull(){...}
Both are same size on my Core 2/gcc 4.4.1.
Overflow condition is not checked on both functions, so an extremely large
string can break these functions so that they don't even notice it.
As we do not care for overflowing on these functions, always keep the sum
using the larger variable around (unsigned long long) on simple_strtoull()
and cast it to (unsigned long) on simple_strtoul(), which then becomes
just a wrapper around simple_strtoull().
