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, Krzysztof
