[PATCH 0/2] arm64: dts: qcom: Introduce Huawei MateBook E 2019

[Jingzhou Zhu]

Huawei MateBook E 2019 is a 2-in-1 tablet shipped with Windows on ARM.
It is one of the early WoA devices powered by Qualcomm Snapdragon 850,
or the sdm850 platform. This series adds mainline Linux support for this
device using device tree.

[PATCH 2/2] arm64: dts: qcom: Add support for Huawei MateBook E 2019

[Jingzhou Zhu]

Add device tree for Huawei MateBook E 2019, which is a 2-in-1 tablet based
on Qualcomm's sdm850 platform.

Supported features:
 - ACSP, CDSP and SLPI
 - Volume Key
 - Power Key
 - Tablet Mode Switching
 - Display
 - Touchscreen
 - Stylus
 - WiFi
 - Bluetooth
 - GPU
 - USB
 - Keyboard
 - Touchpad
 - UFS
 - SD Card
 - Audio (right internal mic and headphone mic not working)
 - Mobile Network

Features not supported yet:
 - Panel Backlight
 - Lid Detection
 - Battery
 - EFI Variable Access
 - Cameras

1. Panel backlight, lid detection and battery will be supported with the
   EC driver upstreamed.
2. EFI variables can only be read with the QSEECOM driver, and will be
   enabled when the driver is fixed.
3. Cameras are tested to work with modified downstream driver, and once
   drivers for these camera modules are included in the tree, cameras can
   be enabled.

Features won't be supported:
 - External Display
 - Fingerprint

1. To make external display work, more reverse engineering may be required,
   but it's beyond my ability.
2. Fingerprint is controlled by TrustZone, meaning direct access to it
   isn't possible.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250924 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
