This series add IRQ handler for low level SOC alert, define a devicetree
binding attribute to configure the alert level threshold and check for
changes in SOC and power supply status for send uevents.
Max17043/17044 have a pin for alert host about low level state of charge and
this alert can be configured in a threshold from 1% up to 32% of SOC.
Tested on Toradex Colibri iMX7D, with a SparkFun Lipo Fuel Gauge module
based on MAXIM MAX17043.
Thanks Krzysztof for your time reviewing it. Let me know what you think about
the fixes.
