I suspect there is something wrong with timings. I believe @maverickjb builds the LN8000 driver as a module. Maybe the load time is necessary.

Needless to say, this breaks fast charging.

Can you please provide this bc it works for me on archlinux arm with edk2-uefi:

EralpCelebi commented 2 months ago

I am using one of your images for Arch Linux on Arm with Plasma I found from the "latest" folder. I tried using the edk2-uefi that was made for the WoA project however I couldn't get it to boot with grub properly (I am assuming this is an Arch Linux package problem more than anything)

I have also checked if the downstream reports a similar problem and it does report the same

ln8000_charger 1-0051: fail to detect ln8000 on i2c_bus(addr=0x51)

however without the rest of the messages and is capable of fast charging.

I currently cannot reproduce your ln8000 problem, for me it detects PD charger and can use it. https://gist.github.com/timoxa0/82a31f245a4d50cfeabdc1aa81257bce

I actually figured out what the problem was thanks to @map220v. Turns out I have one of the early builds of the tablet that used a bq2597x IC instead of an ln8000. It has to be ported from downstream (or taken from the vayu mainline fork if it has the driver) for it to be solved. Thank you for your help.
