As there is no reliable way to identify the chip, it is preferable to
remove the detect callback, to avoid misdetection.
Module parameters are not worth it here, so let's get rid of them and
add an ads7828_platform_data structure instead.
Clean the code by removing unused macros, fixing coding style issues,
avoiding function prototypes and using convenient macros such as

Add support for the watchdog integrated into the SMSC SCH5627 and
SCH5636 superio-s. Since the watchdog is part of the hwmon logical device
and thus shares ioports with it, the watchdog driver is integrated into the
existing hwmon drivers for these.
Note that this version of the watchdog support for sch56xx superio-s
implements the watchdog chardev interface itself, rather then relying on
the recently added watchdog core / watchdog_dev. This is done because
currently some needed functionality is missing from watchdog_dev, as soon
as this functionality is added (which is being discussed on the
linux-watchdog mailinglist), I'll convert this driver over to using
watchdog_dev.

ADM1275 supports a second current limit, which can be configured as either lower

critical current limit.
Also replace error return code EINVAL for unsupported pages with ENXIO as this

With commit c814a4c7c4, the meaning of tempX_max
was changed. It no longer returns the value of bits 8:15 of
MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold
register T1. tempX_max_hyst was added to reflect the value of temperature
threshold register T0.
As it turns out, T0 and T1 are used on some systems, presumably by the BIOS.
Also, T0 and T1 don't have a well defined meaning. The thresholds may be used
as upper or lower limits, and it is not guaranteed that T0 <= T1. Thus, the new
attribute mapping does not reflect the actual usage of the threshold registers.
Also, register contents are changed during runtime by an entity other than the
hwmon driver, meaning the values cached by the driver do not reflect actual
register contents.
Revert most of c814a4c7c4 to address the problem.
Support for T0 and T1 will be added back in with a separate commit, using new
attribute names.

On old CPUs (and even some recent Atom CPUs) TjMax can't be read from
the CPU registers, so it is guessed by the driver using a complex
heuristic which isn't reliable. So let users who know their CPU's
TjMax pass it as a module parameter.

These thresholds can be configured via the sysfs interfaces tempX_max

Add support for NTC Thermistor series. In this release, the
following thermistors are supported: NCP15WB473, NCP18WB473, NCP03WB473,
and NCP15WL333. This driver is based on the datasheet of MURATA.
The driver in the patch does conversion from the raw ADC value
(either voltage or resistence) to temperature. In order to use
voltage values as input, the circuit schematics should be provided
with the platform data. A compensation table for each type of thermistor
is provided for the conversion.

This patch adds a new driver for SMSC SCH5636 Super I/O chips.
The chips include an embedded microcontroller for hardware monitoring
solutions, allowing motherboard manufacturers to create their own
custom hwmon solution based upon the SCH5636.
Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636
based hwmon solution. The sch5636 driver runs a sanity check on
loading to ensure it is dealing with a Fujitsu Theseus and not with
another custom SCH5636 based hwmon solution.
