Battery gauge issue (mainline kernel)

[moonwalkers]

Answering my own post: this was caused by missing drivers in the Debian kernel: enabling CONFIG_TYPEC_FUSB302 (requires CONFIG_TYPEC and CONFIG_TYPEC_TCPM) and CONFIG_SND_SOC_ES8316 makes the type-c port, battery gauge and audio work.

This is currently fixed in Debian sid (from version 5.10.38-1 of linux-image-amd64).

I believe you meant `linux-image-arm64`. What's your experience with it so far? I've seen some instability around WiFi - device likes to disappear out of the blue, haven't noticed any pattern yet. With xmixahx's 5.8.x I had it disappear only occasionally after deep sleep, but with 5.10.0-7 of Debian it can sometimes disappear in the middle of my typing up a message in IM.

One remaining oddness is that the usb-c port does not always work in all orientations: reversing the usb connector can make a usb device work.  Does anyone understand why this is happening?

AFAIK Type-C is not perfectly reversible, and that was brought up before. Somebody on these forums even referred to the USB-C spec not guaranteeing 100% reversible connection. Which seems to me to defeat the purpose, but oh well. I haven't spent enough time reading the spec to tell whether it is an issue with the hardware spec or if it is a software (driver) issue.
