Currently the code checks the interval value when the temperature is
read which is bad for two reasons:
- checking and setting the interval in the get_temp callback is
inaccurate and awful, that can be done when changing the value.
- Changing the thermal zone structure internals is an abuse of the
exported structure, moreover no lock is taken here.
The goal of this patch is to solve the first item by using the 'set'
function called when changing the interval. The check is done there
and removed from the get_temp function. If the thermal zone was not
initialized yet, the interval is not updated in this case as that will
happen in the init function when registering the thermal zone device.
I don't have any hardware to test the changes.

set_mode() is only called when tzd's mode is about to change. Actual
setting is performed in thermal_core, in thermal_zone_device_set_mode().
The meaning of set_mode() callback is actually to notify the driver about
the mode being changed and giving the driver a chance to oppose such
change.

Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled().
Consequently, all set_mode() implementations in drivers:
- can stop modifying tzd's "mode" member,
- shall stop taking tzd's lock, as it is taken in the helpers
- shall stop calling thermal_zone_device_update() as it is called in the
helpers
- can assume they are called when the mode truly changes, so checks to
verify that can be dropped
Not providing set_mode() by a driver no longer prevents the core from
being able to set tzd's mode, so the relevant check in mode_store() is
removed.
Other comments:
- acpi/thermal.c: tz->thermal_zone->mode will be updated only after we
return from set_mode(), so use function parameter in thermal_set_mode()
instead, no need to call acpi_thermal_check() in set_mode()
- thermal/imx_thermal.c: regmap writes and mode assignment are done in
thermal_zone_device_{en|dis}able() and set_mode() callback
- thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a
part of set_mode() callback, so they don't need to modify tzd->mode, and
don't need to fall back to the opposite mode if unsuccessful, as the return
value will be propagated to thermal_zone_device_{en|dis}able() and
ultimately tzd's member will not be changed in thermal_zone_device_set_mode().
- thermal/of-thermal.c: no need to set zone->mode to DISABLED in
of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway

There is a table of Vendor/Model/Version {control data} in this driver,
but outside of the initial probe, the V/M/V is never used again, and
neither are any of the entries for platforms other than the one which
matches the running target.
By simply storing the {control data} for the matched platform, we can
mark the large table __initconst, which reduces the loaded driver size
by 20 percent.

This driver has two module parameters that allow an override of the
checks for matching model and BIOS version. However, both parameters
expect you to choose an entry from the existing list of supported
systems, encoded within the driver itself.
Without the source, such as in a binary distribution, the end user
does not have access to this information, thus rendering the two
module parameters essentially useless.
Add a module parameter that allows the end user to dump the list
of make/model/versions so that they can then pick one that most
closely matches their own system.

Normally, a module parameter for a BIOS check override implies "pretend
you support this version" (and the user will enter their local version).
However, this driver uses the model/BIOS module parameters in a way that
is "pretend my system is the supported model XYZ with BIOS version ABC."
which is less common.
Since the help strings don't make such a distinction, one gets this
somewhat frustrating scenario, where the user sees the error, enters
*their* BIOS version and then gets the same error:

The thermal code uses int, long and unsigned long for temperatures
in different places.
Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.
'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.
Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

Currently you can specify the weight of the cooling device in the device
tree but that information is not populated to the
thermal_bind_params where the fair share governor expects it to
be. The of thermal zone device doesn't have a thermal_bind_params
structure and arguably it's better to pass the weight inside the
thermal_instance as it is specific to the bind of a cooling device to a
thermal zone parameter.
Core thermal code is fixed to populate the weight in the instance from
the thermal_bind_params, so platform code that was passing the weight
inside the thermal_bind_params continue to work seamlessly.
While we are at it, create a default value for the weight parameter for
those thermal zones that currently don't define it and remove the
hardcoded default in of-thermal.

acerhdf has been doing an on-off fan control using hysteresis by
post-manipulating the outcome of thermal subsystem trip point handling.
This patch enables acerhdf to use the bang-bang governor, which is
intended for on-off controlled fans.

Some Acer models require an additional command to turn off the fan after
bios mode has been enabled. Adding new section in bios table to allow
support for those models, by writing an extra "manual mode" register.

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, __devinitdata,
__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.

Some of the thermal drivers using the Generic Thermal Framework
require (all/some) trip points to be writeable. This patch makes
the trip point temperatures writeable on a per-trip point basis,
and modifies the required function call in thermal.c. This patch
also updates the Documentation to reflect the new change.

Due to new supported hardware, of which the actual temperature limits of
processor, harddisk and other components are unknown, it feels safer with
lower fanon / fanoff settings.
It won't change much for most people, already using acerhdf, as they use
their own fanon/fanoff variable settings when loading the module.
Furthermore seems like kernel and userspace tools have been improved to
work more efficient and netbooks don't get so hot anymore.

Would you please consider applying the following patch adding support for
the Aspire 1810TZ BIOS v.1.3314 version to the acerhdf module and avoids the
following error:
acerhdf: unknown (unsupported) BIOS version Acer/Aspire 1810TZ/v1.3314, ple=
ase report, aborting!
Not sure about the other Aspire models, but it seems at least 1810T should
also be updated.

* The acerhdf driver isn't an ACPI driver, so it needs not include
<acpi/acpi_drivers.h>. All it uses is ec_read() and ec_write(), for
which <linux/acpi.h> is sufficient.
* I couldn't find any reason why <linux/fs.h> and <linux/sched.h> were
included.
This should avoid unneeded rebuilds of the acerhdf driver.

Fix resource reclaim in below cases:
1. acerhdf_register_platform() does not properly handle
platform_device_alloc() failure and platform_device_add() failure This
patch adds error handing for acerhdf_register_platform().
2. acerhdf_register_platform() return err with acerhdf_dev == NULL.
as a result, acerhdf_unregister_platform() does not do resource reclaim
in acerhdf_init() error path. This patch adds error handing for
acerhdf_register_platform(), thus correct the error handing path in
acerhdf_init(). goto out_err instead of err_unreg if
acerhdf_register_platform() fail.
3. platform_device_del() should only used in error handling. Current
implementation missed a platform_device_put() in acerhdf_exit. This
patch fixes it by using platform_device_unregister() instead of
platform_device_del() in acerhdf_unregister_platform.
