This patch exports the thermistor resistance-to-temperature tables, so
that the hwmon driver can access them, and also adds the corresponding

A generic driver that implements 'power off by restarting'. The actual
poweroff functionality is implemented through a bootloader, so Linux'

submitting the driver (as well as qnap-poweroff above).

Fix up fairly straightforward conflicts in the ab8500 driver. But since
it seems to be ARM-specific, I can't even compile-test the result..
Today the battery recharge is determined with a voltage threshold. This
voltage threshold is only valid when the battery is relaxed. In charging
algorithm the voltage read is the loaded battery voltage and no
compensation is done to get the relaxed voltage. When maintenance
charging is not selected, this makes the recharging condition to almost
immediately activate when there is a discharge present on the battery.
Depending on which vendor the battery comes from this behavior can wear
out the battery much faster than normal.
The fuelgauge driver is responsible to monitor the actual battery
capacity and is able to estimate the remaining capacity. It is better to
use the remaining capacity as a limit to determine when battery should
be recharged.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitconst,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Let's rename the Device Tree node which contains information about
an attached battery to something more easily readable.
Signed-off-by: Lee Jones <lee.jones@linaro.org>
Currently the AB8500 battery management subsystem receives platform
specific information via two different means depending on how the
platform is booted. If DT is not enabled, a reference to a *_bm_data
data structure containing each platform specific attribute is passed
though platform_data. However, if DT is enabled, then platform_data
is empty and the reference is gained though a DT specific probe
function. There are two issues here 1) the same reference is
being collected each time and 2) the DT way doesn't allow any
provisions to select different platform specific attributes, which
kind of defeats the object.

The platform specific battery management configuration data structure
is currently called 'bat' short for 'battery'; however, it contains
information for all components of the battery management group, rather
than information pertaining to the battery itself - there are other
structures for that. So, in keeping with its structure namesake
'abx500_bm_data', we rename it to 'bm' here. Using similar logic,
we're also renaming 'bmdevs_of_probe' to the more device specific
'ab8500_bm_of_probe'.

We can actually write bmdevs_of_probe to be easier to follow, use
less lines of code and we can even render a variable unused so
that we can remove it completely.
