Subject: [PATCH v7 0/5] power: supply: MAX17040: Add IRQ for low level and alert SOC changes
Date: Sun, 17 Nov 2019 11:13:30 -0300 [thread overview]
Message-ID: <20191117141335.23404-1-matheus@castello.eng.br> (raw)
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 Kozlowski, Lee Jones and Rob Herring for your time reviewing
it.
Changes since v6:
(Suggested by Lee Jones)
- Use relative paths in documentation
Changes since v5:
(Suggested by Krzysztof Kozlowski)
- Rearrange code and add max17040_enable_alert_irq on patch 1/5
- Remove useless dev_info
