Installation

Follow the Installation guide

Note: lk2nd is a hard dependency, without it the mainline kernel will not select the panel.

$ pmbootstrap init # choose Vendor: qcom Device codename: msm8953
$ pmbootstrap install
$ pmbootstrap flasher flash_lk2nd
$ pmbootstrap flasher flash_rootfs

How to enter flash mode

Stock Fastboot: Power on the device with both Power and Volume Down buttons
lk2nd Fastboot: Power on the device. After it vibrates, hold Volume Down

Note: Pressing the keys too early will cause the stock bootloader to handle the key combination. You will end up in the wrong Fastboot interface.

Recovery: Power on the device with both Power and Volume Up buttons

Audio

Speaker is not supported yet.

Parts

Modem

Modem works with ipa-lite on 6.7.0/main 1

Smart Speaker

To use the speaker, the device relies on:

Vendor	Model
Texas Instruments	tas2557 (some useful commits 1 2) Seems to be very similar to tas2559

Fingerprint

Two drivers are available within downstream kernel.

These are not supported yet in mainline kernel.

Vendor	Model
Fingerprint Cards AB	FPC1020 (some useful commits 1 2)
Goodix	GF3208

Sensors

Type	Vendor	Model
Accelerometer / Gyroscope	STMicroelectronics	LSM6DSL (on some variants) 1
Accelerometer / Gyroscope	Bosch	BMI120 (on some variants) 1
Magnetometer / Compass	Asahi Kasei	AK09918C 1
Ambient Light / Proximity	Liteon Opto	LTR579 ALS / PS (same ALS registers of Liteon LTRF216A 1 with no PS part)
Hall	ROHM Semiconductor	BU52061NVX (works as gpio key)

Touchscreen

Type	Vendor	Supported
RMI4	Synaptics	Yes
NT36672	Novatek	Partially (disabled in dts)

NT36672 can be enabled from lk2nd, manual build is needed. https://github.com/msm8916-mainline/lk2nd/blob/main/lk2nd/device/dts/msm8953/msm8953-xiaomi-vince.dts#L23-L47

//touchscreen-compatible = "syna,rmi4-i2c";
touchscreen-compatible = "novatek,nt36525-i2c";

Serial UART

Getting UART output on this device should be pretty straightforward, because pins for serial transfer (TX and RX) are exposed directly on motherboard and are even labeled.
