Note: The Linux kernel often maps 80860F14 to the dw_i2c (DesignWare I2C) driver via the i2c-designware-platform driver.
The secret to how 80860F14 can manage multiple functions lies in the _UID (Unique ID). This integer value, attached to the main ID, tells the kernel exactly which hardware block is being addressed. The Linux kernel uses a table to match _HID and _UID pairs to the correct driver slot. Acpi 80860f14
Because this specific controller is tied to System-on-Chip (SoC) microarchitectures—most notably , Cherry Trail , and early Braswell platforms—it is widely distributed across several portable or low-power form factors: Note: The Linux kernel often maps 80860F14 to
