ACPI Hardware ID 80860F14: A Case Study in Intel SoC Power Management

Abstract
The ACPI Plug and Play Hardware ID 80860F14 corresponds to a proprietary Intel device found primarily on Bay Trail and Cherry Trail system-on-chips (SoCs). This paper examines the device's identification, its role in power management and I2C controller operation, and the challenges it presents for open-source operating systems. Acpi 80860f14

Note: The Linux kernel often maps 80860F14 to the dw_i2c (DesignWare I2C) driver via the i2c-designware-platform driver.
