NCT6775, NCT6776, and NCT6779 have a number of variants with the same chip ID but different chip labels. Add text "or compatible" to the message displayed when the driver is loaded and rephrase the Kconfig entry to reflect that it also supports compatible chips.

2013-04-08hwmon: (pmbus/lm25066) Report VAUX as vmonGuenter Roeck1-8/+8
So far the driver reported the voltage on VAUX as "vout2". This was not entirely appropriate as it is not an output voltage, and complicates the code. Use the new virtual "VMON" register set and report the voltage as "vmon" instead. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2013-04-08hwmon: (pmbus/ltc2978) Clean up documentationGuenter Roeck1-22/+19
Some sysfs attributes are only supported on LTC2978 and not on LTC3880. Update documentation to reflect which attributes are supported for which chips. Output current attributes supported on LTC3880 were described as providing input current values. Fix text to reflect that the attributes provide output current values. "reset history" attribute descriptions were misleading and seemed to imply that all history was reset when writing a single attribute. Replace with more accurate text. Replace 'internal temperature" with "chip temperature". Temperature limits not only apply to the chip temperature, but also to external temperatures on LTC3880, so remove the word "chip" from the attribute description.

2013-04-08hwmon: Driver for Nuvoton NCT6775F, NCT6776F, and NCT6779DGuenter Roeck1-0/+81
This driver will replace the w83627ehf driver for NCT6775F and NCT6776F, and provides support for NCT6779D. This patch provides support for voltage monitor attributes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-08hwmon: (adt7410) Add support for the adt7310/adt7320Lars-Peter Clausen1-17/+30
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map layout is a bit different, i.e. the register addresses differ between the two variants, but the bit layouts of the individual registers are identical. So both chip variants can easily be supported by the same driver. The issue of non matching register address layouts is solved by a simple look-up table which translates the I2C addresses to the SPI addresses. The patch moves the bulk of the adt7410 driver to a common module that will be shared by the adt7410 and adt7310 drivers. This common module implements the driver logic and uses a set of virtual functions to perform IO access. The adt7410 and adt7310 driver modules provide proper implementations of these IO accessor functions for I2C respective SPI.

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.
