* | | | hwmon: (nct6775) Enable both AUXTIN and VIN3 on NCT6776Guenter Roeck2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per datasheet, VIN3 and AUXTIN share the same external pin. However, there is no clean way to detect this condition. Furthermore, both are reported by the BIOS on Supermicro C7H61. It may thus be possible that chip revisions exist where both attributes are supported at the same time. Better play safe and report both. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
