Subject: [PATCH v2 0/2] Hwmon driver for MAX31827 temperature switch

There are new functionalities: max_alarm, min_alarm and update_interval.

Modified enable attribute: it switches between 1Hz periodic conversions
and shutdown mode.

When requesting a temperature read in shutdown mode 1shot is triggered,
the driver waits until the conversion is completed and then displays the
read value.

Added new write_alarm_val function which puts the device in shutdown
mode, modifies the value of an alarm attribute and the reenables the
device with the previous configurations. I used more bitwise operations
in this functions instead of regmap_update_bits, because this way only 2
write and 2 read operations are performed. With regmap_update_bits 3
write operations and 2 read operations would be performed.

Added support for the other 2 chips from the datasheet: max31828,
max31829.

Added documentation for the driver.
