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 for send uevents.
Max17040 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 Raspberry Pi Zero W, with a SparkFun Lipo Fuel Gauge module based on MAXIM MAX17043.
