[PATCH v8 0/5] power: supply: MAX17040: Add IRQ for low level and alert SOC changes

[Matheus Castello <matheus@castello.eng.br>]

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.

Thanks Krzysztof Kozlowski, Lee Jones, Rob Herring and Sebastian Reichel for
your time reviewing it.

Changes since v7:
(Suggested by Sebastian Reichel)
- Fix unrelated change
- Use device_property_read_u32() and simplify the code
- Check the irq and of_device_is_compatible in the first patch

Changes since v6:
(Suggested by Lee Jones)
- Use relative paths in documentation
