Subject: Trying to improve a kernel driver
Date: Tue, 10 Aug 2021 09:24:43 +0200 [thread overview]
Message-ID: <50d3f5fc-64b6-99fd-3992-9eb9f2843746@marangoni.cc> (raw)
Hello,
I'm new to developing kernel drivers and want to improve the driver of
the axp209 power management chip. I've read the documentation about the
Linux power supply class
(https://www.kernel.org/doc/html/latest/power/power_supply_class.html)
and there it says: "Power supply class is extensible, and allows to
define drivers own attributes.". The Problem is I couldn't find an
example of how to add own attributes. My goal is to have an own
attribute showing up at /sys/class/power_supply/axp20x-battery/
If someone can give me a hint, extended documentation or a better place
to ask, that would be great!
