Xie Xiaobo 5510e62a66 hwmon: Add MCP3021 ADC driver
Add I2C driver for MCP3021 that is an ADC chip from Microchip.
The MCP3021 is a successive approximation A/D converter (ADC)
with 10-bit resolution.
The driver export the value of Vin to sysfs, the voltage unit is
mV. Through the sysfs interface, lm-sensors tool can also display
Vin voltage.

Uwe Kleine-Koenig 0c2732152a hwmon: (mc13783-adc) Add support for the MC13892 PMIC
Based on a patch by David Jander that mostly did s/mc13783/mc13xxx/ .

Additionally use dev_get_drvdata instead of to_platform_device +
platform_get_drvdata in mc13783_adc_read (spotted by Jean Delvare).

Linus Torvalds 31f6765266 hwmon changes for v3.4
Mostly cleanup. No new drivers this time around, but support for several chips
 added to existing drivers: TPS40400, TPS40422, MTD040, MAX34446, ZL9101M,
 ZL9117M, and LM96080. Also, added watchdog support for SCH56xx, and additional
 attributes for a couple of drivers.

Hans de Goede 312869ec93 hwmon: (sch56xx) Add support for the integrated watchdog (v2)
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.

Jean Delvare 16b5dda22e hwmon: (it87) Add IT8728F support
Until we get a datasheet for the IT8728F, treat it as fully compatible
with the IT8721F, as it seems to work reasonably well.

This closes kernel bug #27262.

Jean Delvare d216f6809e hwmon: (lm63) Expose automatic fan speed control lookup table
The LM63 and compatible devices have a lookup table to control the fan
speed automatically. Expose it in sysfs. Values are cached for 5
seconds, independently of the other register values to avoid slowing
down "sensors". We might make the table values writable in the future.

Guenter Roeck f4af6fd6e2 hwmon: (coretemp) Don't use threshold registers for tempX_max
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.
