[PATCH v3 0/4] Introduce HONOR MagicBook Art 14 Snapdragon device tree

[Konstantin Shabanov <mail@etehtsea.me>]

Introduce support for the HONOR MagicBook Art 14 Snapdragon laptop.
This version is based on the initial work by Kirill A. Korinsky [1]
and Valentin Manea [2].

I'm using it with an external display connected to the HDMI port as
a daily driver for some time now.

eDP support is broken (screen is eigher grey or grey with noise), thus,
keeping it disabled for now.

Supported:

- Sound (with alsa-ucm-conf config [5])
  - Speakers
  - Headphone jack
- Bluetooth
- Battery
- HDMI
- DP over USB-C
- Touchpad
- Keyboard (with backlight)
- Touchscreen
- WiFi
- USB-C ports
- USB-A port
- UFS
- H/W accel

Untested:

- Camera
- Fingerprint reader
- Sleep/Suspend

Broken:

- eDP

ACPI dumps are available in aarch64-laptops repo [3].
