Subject: [PATCH v1 0/5] platform/x86: ayaneo-ec: Add Ayaneo Embedded
 Controller platform driver

This series introduces a platform driver for Ayaneo devices, ayaneo-ec.
This driver provides hwmon support, power management, and module management
(for the new Ayaneo 3 device). Module management is done through the new
firmware attributes sysfs interface.

Luckily, all Ayaneo devices with an ACPI mapped EC use the same registers.
Older devices also use a memory mapped region for RGB[1], but that is
replaced by HID in the new Ayaneo 3. Therefore, this allows for a simple
driver design that provides robust future support. The memory mapped region
can be upstreamed as a different RGB driver in the future or remain
out-of-tree[1].

This change also allows cleaning up the oxpec driver, by removing Ayaneo
devices from it. In parallel, charge limiting is added for these devices.
