Bug#927163: linux-image-4.19.0-4-amd64: Missing modules for AXP288 power fuel gauge driver
Package: src:linux
Version: 4.19.28-2
Severity: wishlist
Dear Maintainer,
In #895129 axp288_fuel_gauge was included as a module for x86 platforms.
After that the battery icon was actually showing on my Cherrytrail tablet.
But since then, this has again stopped working (and I'm not sure it was
actually reporting a correct state), and also it never detected the AC power
being connected. I believe there are still some missing stuff to get this
working.
Looking at a commit for ARM I can see this:
https://salsa.debian.org/kernel-team/linux/commit/0138e6bc4eedd8c10ad637e742a4fe6c625c6def
There seems to be some additional things in there.
AXP20X_ADC, CHARGER_AXP20X, BATTERY_AXP20X, GPIO_AXP209,
AXP288_CHARGER, EXTCON_AXP288, AXP288_ADC
Also, looking at the kernel source, there seems to be a case where
the axp288_fuel_gauge module waits for axp288_adc to load (this module
is currently not built for x86):
https://github.com/torvalds/linux/blob/dc4060a5dc2557e6b5aa813bf5b73677299d62d2/drivers/power/supply/axp288_fuel_gauge.c#L774
This probing code was appearantly added late 2017 (so, possibly that code
wasn't in the kernel that was first released in Debian with the
axp288_fuel_gauge module on x86, which might possibly explain why I saw
the inaccurate reading (I recall it always reporting 100%).
Thanks,
//Marcus
