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.

2.47.3Add 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.

Did you post the board data to the ath10k@ mailing list?
See https://wireless.docs.kernel.org/en/latest/en/users/drivers/ath10k/boardfiles.html
Also if possible, please include output from BT and WiFi probing to the
commit message.
