Add an initial devicetree for the Huawei Matebook E Go, which is based on
sc8280xp.
There are 3 variants, Huawei released first 2 at the same time.
Huawei Matebook E Go LTE(sc8180x), codename should be gaokun2.
Huawei Matebook E Go(sc8280xp@3.0GHz), codename is gaokun3.
Huawei Matebook E Go 2023(sc8280xp@2.69GHz).
We add support for the latter two variants.
This work started by Tianyu Gao and Xuecong Chen, they made the
devicetree based on existing work(i.e. the Lenovo X13s and the
Qualcomm CRD), it can boot with framebuffer.
Original work: https://github.com/matalama80td3l/matebook-e-go-boot-works/blob/main/dts/sc8280xp-huawei-matebook-e-go.dts
Later, I got my device, I continue their work.
Supported features:
- adsp
- bluetooth (connect issue)
- charge (with a lower power)
- framebuffer
- gpu
- keyboard (via internal USB)
- pcie devices (wifi and nvme, no modem)
- speakers and microphones
- tablet mode switch
- touchscreen
- usb
- volume key and power key
Some key features not supported yet:
- battery and charger information report (EC driver required)
- built-in display (cannot enable backlight yet)
- charging thresholds control (EC driver required)
- camera
- LID switch detection (EC driver required)
- USB Type-C altmode (EC driver required)
- USB Type-C PD (EC driver required)
I have finished the EC driver, once this series are upstreamed,
I will submit a series of patches to enable EC support.
