Hosts the 0x221E linux distro kernel. https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.16.y 2025-03-03T08:55:36Z 2025-03-03T08:55:36Z Pengyu Luo mitltlatltl@gmail.com 2025-02-14T18:06:55Z urn:sha1:7636f090d02e791918bb3c924e695880123d0c59 There are three variants of which Huawei released the first two simultaneously. Huawei Matebook E Go LTE(sc8180x), codename seems to be gaokun2. Huawei Matebook E Go(sc8280xp@3.0GHz), codename must be gaokun3. (see [1]) Huawei Matebook E Go 2023(sc8280xp@2.69GHz), codename should be also gaokun3. Adding support for the latter two variants for now, this driver should also work for the sc8180x variant according to acpi table files, but I don't have the device to test yet. Different from other Qualcomm Snapdragon sc8280xp based machines, the Huawei Matebook E Go uses an embedded controller while others use a system called PMIC GLink. This embedded controller can be used to perform a set of various functions, including, but not limited to: - Battery and charger monitoring; - Charge control and smart charge; - Fn_lock settings; - Tablet lid status; - Temperature sensors; - USB Type-C notifications (ports orientation, DP alt mode HPD); - USB Type-C PD (according to observation, up to 48w). Add a driver for the EC which creates devices for UCSI and power supply devices. This driver is inspired by the following drivers: drivers/platform/arm64/acer-aspire1-ec.c drivers/platform/arm64/lenovo-yoga-c630.c drivers/platform/x86/huawei-wmi.c Also thanks for reviewers' working. They have made this patch improve a lot.
