pdx213-temp

Some notes on my work getting Mobian to run on the Xperia 10 III (codename pdx213).

Status

Device Tree Status

Component	Status	sent to sm6350-mainline?
ADSP	✅	✅
Battery (percentage and temperature)	✅	✅
Bluetooth	✅	✅
Calls
Camera	to do
CDSP	✅	✅
Display Panel	✅	✅
DP via USB-C	low priority
Fast Charging	to do, low priority
Fingerprint Reader	low priority, probably not supported by the kernel anyway
Flashlight	✅	✅
GPS
IPA	✅	✅
microSD	✅	was already part of upstream
Modem	✅ (requires UFS, but for testing I could work around this)	✅
NFC	to do, low priority
RTC	added, needs testing	✅
Sound	to do
SMS
Thermals
Touch	occasionally does not work	was already part of upstream
UFS	broken, need help
USB-C	?
Wifi	✅ (requires modem)	✅
Vibration	to do, low priority

No status means I haven't even had a look at that component.

So far no work has been put in supporting the sensors (accelerometer, magnetometer, ambient light, ...).

Where To Help

Thermal Sensors / Thermal Zones (no idea what I need to do)
PMIC
Camera
vibration module
NFC
UFS
USB-C

And I will also need help with upstreaming the changes to the kernel, can someone else please do that? Thanks.

Kernel Work

I'm currently working here: https://github.com/erebion/linux/commits/pdx213-wip/

Current goal: Making the usable Later goal: Trying to add everything else that can be added without writing new drivers

Note: I'm rebasing occasionally to make sure it does not become too chaotic, so pulling from that repo will lead to merge conflicts.

Mobian Work

Not much that is required in terms of changes, mainly adding the device to Mobian recipes.

To Do:

Push changes for Mobian recipes to git
Add droid-juicer config
Amend qcom-phone-utils package (initramfs hooks, perhaps more)
