Lars-Peter Clausen	4b5e536b0e	hwmon: (adt7x10) Add alarm interrupt support ... This allows an userspace application to poll() on the alarm files to get notified in case of a temperature threshold event.

Lars-Peter Clausen	51c2a4871c	hwmon: (adt7410) Add support for the adt7310/adt7320 ... 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.
