platform: Add ARM64 platform directory Some ARM64 based laptops and computers require vendor/board specific drivers for their embedded controllers. Even though usually the most important functionality of those devices is implemented inside ACPI, unfortunately Linux doesn't currently have great support for ACPI on platforms like Qualcomm Snapdragon that are used in most ARM64 laptops today. Instead Linux relies on Device Tree for Qualcomm based devices and it's significantly easier to reimplement the EC functionality in a dedicated driver than to make use of ACPI code. This commit introduces a new platform/arm64 subdirectory to give a place to such drivers for EC-like devices. A new MAINTAINERS entry is added for this directory. Patches to files in this directory will be taken up by the platform-drivers-x86 team (i.e. Hans de Goede and Ilpo Järvinen) with additional review from Bryan O'Donoghue to represent ARM64 maintainers.

platform: arm64: Add Acer Aspire 1 embedded controller driver Acer Aspire 1 is a Snapdragon 7c based laptop. It uses an embedded controller to perform a set of various functions, such as: - Battery and charger monitoring; - Keyboard layout control (i.e. fn_lock settings); - USB Type-C DP alt mode HPD notifications; - Laptop lid status. Unfortunately, while all this functionality is implemented in ACPI, it's currently not possible to use ACPI to boot Linux on such Qualcomm devices. To allow Linux to still support the features provided by EC, this driver reimplments the relevant ACPI parts. This allows us to boot the laptop with Device Tree and retain all the features.

platform: arm64: add Lenovo Yoga C630 WOS EC driver Lenovo Yoga C630 WOS is a laptop using Snapdragon 850 SoC. Like many laptops it uses an embedded controller (EC) to perform various platform operations, including, but not limited, to Type-C port control or power supply handlng. Add the driver for the EC, that creates devices for UCSI and power supply devices.
