This patch adds the support for following battery properties
to max17042 fuel gauge driver.

POWER_SUPPLY_PROP_TEMP_ALERT_MIN
POWER_SUPPLY_PROP_TEMP_ALERT_MAX
POWER_SUPPLY_PROP_TEMP_MIN
POWER_SUPPLY_PROP_TEMP_MAX
POWER_SUPPLY_PROP_HEALTH

I wonder, have you tested the patch? After booting on Trats2 device
(max77693 which identifies itself as 17047-like) the values are:
POWER_SUPPLY_TEMP_ALERT_MIN=1280
POWER_SUPPLY_TEMP_ALERT_MAX=1270
POWER_SUPPLY_TEMP=257
This is okay, datasheet says that register after booting will have
value of 0x7f80.

However setting them to some value which should trigger interrupts
(like 300 for MIN or 200 for MAX) does not trigger the interrupt. I
added a printk in max17042_thread_handler().

Is the temperature alert feature working?

Best regards,
