    Subject[PATCH v3 4/4] arm64: dts: qcom: Add Acer Aspire 1
    Date
    Acer Aspire 1 is a WoA laptop based on Snapdragon 7c gen1 platform.

    The laptop design is similar to trogdor in the choice of primary
    components but the specifics on usage of those differ slightly.

    Add the devicetree for the laptop with support for most of the
    hardware present.

    Changed in v2:
    - Various styling, ordering and node naming issues fixed. (Krzysztof)

    Changed in v3:
    - Kepp camcc on, wakeup on touchpad, minor style issues. (Konrad)
