Nokia 8110 4G (nokia-argon)

Display
The display is connected via SPI and works with the tinydrm panel-mipi-dbi driver. It is usable even without GPU or MDP3 support. MDP3 seems to be unused on this device because it isn't connected to the display in any way. Backlight control also works.

Battery
Uses the voltage mode BMS driver, see Wileyfox_Swift_(wileyfox-crackling) for warnings and more information.

Flashing
EDL mode can be entered by pressing the Up and Down keys while plugging in or turning on the phone. Use the loader from https://edl.bananahackers.net and the edl.py fork at https://github.com/andybalholm/edl.

Partitions can also be written directly using dd on rooted devices.

Installation
Install the lk2nd branch from https://github.com/msm8916-mainline/lk2nd/pull/214 into the boot partition. After that, you can use pmbootstrap flasher commands to flash postmarketOS via the fastboot interface provided by lk2nd.

Because this lk2nd is based on the experimental-tmp branch and does not support fs-boot yet,  is required even when booting from an SD card.
