2013-04-08hwmon: (ad7314) use spi_get_drvdata() and spi_set_drvdata()Jingoo Han
Use the wrapper functions for getting and setting the driver data using spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we can directly pass a struct spi_device. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2013-04-08hwmon: (nct6775) Expand scope of supported chipsGuenter Roeck
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) Clamp limit attributesGuenter Roeck
Limits on all supported sensors and chips have to be within 0..0x0fff, and limits are always positive. Clamp written values in chip driver. Also clear value cache to ensure that the actually written value is read back and reported correctly. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-08hwmon: (pmbus/lm25066) Report VAUX as vmonGuenter Roeck
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 Roeck
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: (pmbus/ltc2978) Code cleanupGuenter Roeck
Use u16 instead of int to store cached limit attributes. This reduces allocated data size per driver instance by 48 bytes. Use defines for the number of pages supported by individual chips.

2013-04-08hwmon: (adt7410) Add support for the adt7310/adt7320Lars-Peter Clausen
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.

2013-04-08hwmon: (adt7410) Don't re-read non-volatile registersLars-Peter Clausen
Currently each time the temperature register is read the driver also reads the threshold and hysteresis registers. This increases the amount of I2C traffic and time needed to read the temperature by a factor of ~5. Neither the threshold nor the hysteresis change on their own, so once we have read them, we should be able to just use the cached value of the registers. This patch modifies the code accordingly and only reads the threshold and hysteresis registers once during probe.
