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.
